Good day, Dr. M. Vaigundamoorthi. I'm Arjun. I've had a look through your background and your professional record. I'm interested in hearing more about your work and how you see yourself fitting in here with our faculty. Ready to start?

Please start by introducing your professional journey in academia.

Hello.

Hi. Yes, Sir.

OK.

Oh, yes, yes, fine. Hello.

Hello.

Yeah, let me introduce myself. Let me introduce myself. I'm Dadrium Vaikunamurthy working as a professor in Savita University Engineering, College of Engineering, Chennai. I have completed my ME and PhD from College and Guindy Chennai. It is one of the reputed institute in India and I have done my undergraduate from College of Engineering. It is under Madhuri Kamaraj. University is a common university. I have 20 years experience in teaching. My area of interest includes hard on his control application to renewal system.

Dr. Vaigundamoorthi,

Control system now. Now I am in Chennai. Thank you.

Thank you for the introduction, Dr. Vaigundamoorthi. I appreciate the overview of your background and areas of interest. Let's dive in and assess your fit for the role. To start, let me verify your expertise in Power Electronics, Power Systems, and Control Systems. Could you describe a scenario where you applied your knowledge of control systems to address a challenge in renewable energy systems? Please be specific about the methodologies or tools you employed.

Sir, my area conditions power attorneys and control system. So power is very much recent.

Field which is applied to the system to control the decent AC, power and electrical vehicles motion. Motion control.

My area include a coordination drive system Sir.

I it's a fine. I have done research on power running so fabrication to solar energy, solar energy system. In that I have used a chip converter to control the maximum per binder PowerPoint tracking from the solar PV. I have used the converter. I have used actually adaptive perturbed observer algorithm to trace the maximum power and I have implemented using advanced system microcontroller.

I have investigated non linear dynamics which is available in the solar PV system and I have used instead of PWM, Kyotic PWM. I have used it to control the duty cycle of the switch so that the EMA is very much reduced in the input input to inductor current so that your solar PV system is more EMC. That I made you feel electromagnetic commodity. So I have used actually equilibrium to control the switch of the mass fed so that EMI is very much reduced. So I have applied various power control methods like PWM, Samsung like so many controlled methods I have applied on the converter to control the output voltage of the solar PV system. So that the EMA was tested using listen. So that very much EMA is.

Thank you for sharing that insight, Professor. To delve deeper into your expertise, could you elaborate on your specific contributions or innovations in control applications for renewable energy systems or electric vehicle motion control?

It's reduced by using this equilibrium. So this is my contribution of my research. Now I'm working on high gain DCDC converter.

Understood, Professor. Thank you for the detailed explanation—it’s clear you’ve invested considerable effort in optimizing solar PV systems through innovative control methods. Let’s now turn to your abilities as an educator. Given your extensive experience, could you share how you approach the task of teaching complex control system concepts to undergraduate students, ensuring they both understand the theory and apply it in practical scenarios?

Yes, OK, fine. So I have used actually experimental based, uh, teaching, uh, for students so that students can understand, uh, the concept very clearly. I will demonstrate a project based learning also on power transition control system applied to application of solar PV system so that students can be able to simulate and do the hardware product in their own so that they can develop their skill sets in the area of auto running application to the system. So I, I will apply 2 methods extra model.

OK, project based already. So that sort of can clearly understood, uh, the concept behind the, uh, power techniques and uh, control application to solar system.

Yes, yes, Sir.

Example I will take one example. I will take a small example. Let me take a D seduc converter like a bucket motor boost converter, buck boost converter converter converters. We will be demonstrating what is happening principle behind the DCDC converter concept. Then we will go for MATLAB simulation. In the simulation we will do how to implement the converter and control aspects to control the solar power. Solar power using solar panels so that by controlling the switch we can able to control the. Output voltage of the uh converters and there way we can control the uh power flow uh from the uh, solar PV. So the same can be implemented on the projects. So we will using some uh uh hardware uh designs, uh. We will implement uh all the converters and we will incorporate with the solar P panel and we will include uh MPPD tracking and we will control all the solar P output voltage. Then we will apply uh some control methods so that uh, we we can control the EMA of the.

How do you evaluate the students'

Entire system uh, we will uh, we will apply PWM control KYWM, our uh soft to see, like you said, VSSRCS to control the uh output voltage of the solar PV. So in this way, we will integrate the students to land experimental and uh practical oriented uh PC for our students to enhance their skill.

Thank you.

Yes, fine Sir, Sir, first we will find what is the recent reported converters or inverters by doing literature survey and accordingly we will pick the topics to obligation to the solar PV system and the same after based on the literature review and we will identify which converter is suitable for the high. There is like high, high gain converter for MPPT cycles and then the same will be given to the students.

For analysis, I'll be doing small technologies and corporate specifications. We will, you will go for implementation on MATLAB and we will do experimentation and, uh, demonstration on the laboratory so that students can inculcate project based learning, uh, to enhance their skills.

Before concluding this topic, Professor, I'd like to verify one additional area of competence. Could you elaborate on your process for guiding student research projects, particularly in topics like Power Electronics

Yes, Sir.

Yes Sir. Both are interlinked power techniques application to the system. We will do all the control aspects. So in that area like power rings, control plus electrical vehicles, we can identify projects that can be given to the students to implement so that students can enhance their skill sets up.

Now, Professor, let's move on to another important aspect. Could you discuss your experience with publishing research in reputable journals and how you align your work with cutting-edge advancements in power electronics, control systems, or renewable energy?

OK, fine. Now I have used actually uh loop converter and Sue converter uh enhance enhance the password suconverter so that the output voltage is very uh high enough is obtained so that can be implemented. Uh for the high gain converter that can be implemented on power ready circuits to track the maximum power so that output voltage is very much higher is achieved. There can be uh extra monitored with the help of students so that this can be delivered.

Understood, Professor. Could you also share a specific example of your work that has been published in a well-regarded journal, highlighting the research problem, your methodology, and its contribution to the field?

Definitely.

The Frank is speaking. No, Sir, That episode is not given to me. If it is, if I'm appointed in the VAT, I will try to find some industry to cooperate this work. Yes, Sir. Thank you.

Thank you for your honesty, Professor. It's good to see your willingness to pursue industry collaborations in the future. Lastly, let me quickly verify your communication and teaching techniques. Could you briefly explain how you would simplify the concept of MPPT (Maximum Power Point Tracking) in solar photovoltaic systems to a beginner-level audience?

Yes, fine MPPD tracking, nothing but maximum PowerPoint tracking. So by using this method we can track the maximum power from the solar panel. So in that we will measure old days in current using old days in current sensors and we will do multiplication of what is in current so that power is obtained. We first calculate what is the personal power available by dragging MPPD from a solar PV by using some DCDC converter by adjusting the 2D cycle of the switch. Once present power is compared then.

After some time, uh, we will identify what is the current, uh, we'll compare accordingly. The pulse will be generated. We should be given to the, uh, DC converter so that, uh, the new permanent will be updated automatically. So like that, the process will be continued. Finally, we will reach the maximum power where, uh, we will, we will obtain, uh, VM and IEM. So that, which is a very high power, which is uh, tracking from the solar PV that can be given to the load. So this in this way we will do like this. We have many algorithms like facility algorithm, incremental algorithms available.

So out of this we have. I have chosen actually. Now I have expected algorithm where the personal bug and previous bug are compared accordingly. They're due to segment suggested which should be given to the power switch so that the.

Based on the duty cycle, the output voltage is raised for the solar PV. You should be given to the load.

Thank you.

Thank you, Professor, for the detailed explanation. Your ability to make complex ideas accessible is certainly valuable in teaching. That concludes my questions. If there’s anything else you’d like to add, please feel free to share.

Martin.

So can you, can you one second, Sir, please?

Of course, Professor. Please take your time. Let me know how I can assist further.

What is the question? One second please, Sir.

Yes Sir, maximum cover is available not in all the points in the PV curve of the solar panel. At one point only we can actually maximum where the voltage is VM and the current is I am. So in order to trace this VM and I am we will use some algorithms like algorithm algorithm, personal algorithm like that many algorithms are recorded in the survey sounder which I have taken adaptive. Algorithm where when the MPP is far away, the subset is very high.

Certainly, Professor. The last question was regarding how you would explain the concept of MPPT (Maximum Power Point Tracking) in solar photovoltaic systems to a beginner-level audience. You’ve already provided a good explanation. Would you like to clarify or add more to your answer?

OK, very high. So easily we can raise the maximum very close to actual maximum power OK by adjusting the go to cycle in order to identify the maximum power near to the maximum PowerPoint. The subset is very small so that accurate MPP point is noted which can be given to the data given to the converter. I just want I will do second so that the maximum over is extracted from the solar PV which will be given to the given to the load. So normally we are using. Bug boost converter.

As a everybody tracker like uh converter or two converter, Sebi converter or flabby converter preferred acting as a maximum point tracker. And we will apply some algorithms like algorithm adaptive absorb and microcontroller so that the algorithm trace every time it will sense what is the old is available, what is the current available. It will do multiplication so that power is calculated and present power and previous server are compared accordingly the two to cycle is predicted.

Second, the first should be given to the power converter. They should serve the power converter so that the exact maximum power is extracted from the solar PV. In this uh procedure, when the MPP is uh, maximum performance is far away, their subsize is very long. OK when they be near to the MPP, there's maximum PowerPoint their surface very small so that we can extract actual true power. There is a maximum power from this solar PV there can be given to the load. So this is a concept begins the maximum PowerPoint tracking or the solar PV system. Yes Sir. Thank you that work only I have done in my previous research work I I have applied various control methods OK, in order to enhance the. EMI or EMC in add reduce the EMI and increase the EMC.

I have played various control methods. For example instead of supplying PWM, I have supplied kinetic PWM so that the output voltage you know what we are tracking from the solar PV is high highly EMC There is which is having very less EMI. OK and I have applied one more mathematical that is a methods control methods like.

CS user CS on the converter while doing while tracking the maximum power so that.

Uh. The output voltage is uh, more EMS.

Thank you.

Thank you, Professor, for elaborating further on your research. It is evident that you have a deep understanding of MPPT and have explored innovative control methods to improve the performance and efficiency of solar PV systems. That concludes my queries. If you have nothing more to add, do you confirm that you'd like to end the interview?

So, Gordon.

One more time, Sir.

So can you, can you ask the question one more time, Sir, please?

Of course, Professor. If there’s anything else you’d like to share or discuss, please feel free to take your time.

Certainly, Professor. The last question was regarding how you would explain the concept of MPPT (Maximum Power Point Tracking) in solar photovoltaic systems to a beginner-level audience. Let me know if you'd like to refine or expand your explanation further.

Hello.

Hello.

Yes, Sir.

So what is the last question you asked, Sir? Can you repeat again?

Let me know how I can assist you further, Professor.

I have delivered. Uh, uh, yeah, yes, please.

Yes.

Yes.

Yes, Sir, I, I interrupted it. Sorry to interrupt. Please ask the question one more time. I will respond properly. Thank you.

Yes, I have explained very clearly about the maximum PowerPoint tracking to track the maximum power from the solar PV. While there is, we will measure what is the voltage in current by using what is in current sensors and we will calculate what is the present power available and after some time we will trace the same procedure and we will compare accordingly. Based on the power calculation press and power previous cover, we will generate duty cycle. There is a pulse which will be given to the. Switch switches of the power converter so that.

No problem, Professor. The last question was: How would you explain the concept of MPPT (Maximum Power Point Tracking) in solar photovoltaic systems to a beginner-level audience?

Yeah, the output voltage is subtracted from the solar PV.

Baby, this is a procedure behind the MPPD. OK, so in that we are using adaptive uh, cut up and observe algorithm algorithm where customer and previous server are compared accordingly. The pulse is generated to control the switch of the DCC converter so that we can trace maximum power. So this is the concept behind the APPD.

OK, so like this MPPT techniques they have several methods are available like facility we can implement, we can implement incremental and conductance algorithm to test the maximum power. So in my message I have upgrade adaptive put up and absorb algorithm. There is whenever the operating point is very far away from the actual MPP rest of size is very large and whenever the MPP operating point is very close to the MPP. So the the subset is very small so that we can.

Raise the maximum power from the solar panel by adjusting the duty security of the solar there is of the power converter. So power converters plays a key role. Nothing but integral tracker. Normally we are using a bug boost converter. Out of bug boost converter, we have two converter civic and outers are preferred. Preferred to trace the maximum power from the solar PV. Yes Sir, thank you.

Thank you, Professor, for providing such a comprehensive and detailed explanation of MPPT and the methodologies behind it. It’s clear that you have both theoretical knowledge and practical insights into the subject, which is valuable for teaching and guiding students. If there’s nothing else you’d like to add, do confirm whether we can conclude the interview.

That is a miscellaneous algorithms like reinforcement algorithm on the application of with solar view system. Now I I'm working in that area miscellaneous. So reinforcement learning I have upgraded like action, success, reward procedure is separated on the ambiguity tracker. So in that area I'm only I'm working nowadays. Thank you Sir.

Yes Sir, I I have a screen search to to implement.

Also also I'm developing a high gain converters to enhance the output voltage of the converter by including many storage elements like capacitor combination so that EMC. Also I'm working how by descending a proper filters and controllers. How to get a perfect converter with EMC with this application to the solar TV system in that area I'm working nowadays?
