Good day, Dr. Joly M. 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, are you there?

Hello. Good afternoon, Sir.

Good afternoon, Professor. Please start by introducing your professional journey in academia.

Yes.

Feel free to begin with an overview of your academic journey whenever you're ready.

Sad.

Yes.

Dr. Joly, I’ve reviewed your resume and the job description. Let's begin evaluating your suitability for the Professor position by focusing on the required skills and qualifications step by step. Starting with your expertise: Could you explain your understanding of Power Electronics and its applications in Renewable Energy Systems? Be as specific as possible.

Sir, uh, I have been working with this industry for 23 years. Sir, I was working as associate professor in Savita Engineering College for the past 15 years. And currently I am working with the Universal Engineering College as HOD and professor for the past four years. I am continuing with this job. Uh, and I have done my Btech from my electrical engineering from NIT Calicut and I have done my PhD in.

Noi city so about the MI M tech degree is in power electronics and industrial drives. So umm, as an electrical engineer in power electronic job. It is very uh interesting and power electronics is the emerging trend nowadays because electrical vehicles and uh, the quantum theory, everything is coming into practice and semiconductor devices are coming into picture nowadays.

And this, this creates a more value to the power electronic systems because the systems in itself, the efficiency and overall power of the system got improvised due to the power semiconductor devices and Igpt MOSFET, et cetera. So this contributes everything to the industry and as well As for the educational background.

It’s clear you have substantial experience and a deep academic background. You touched on some advancements like electrical vehicles and improved semiconductor devices. How would you go about explaining the operation and advantages of an IGBT to undergraduate students in a classroom setting?

Igpt and MOSFET are the power electronic devices which we are using in electrical vehicles and all and these these power devices are extremely low cost and also it is very efficient. We'll be getting the Igpt and MOSFET as the voltage controller and power controller device and this will be using in the semiconductor industry as well as. The electrical vehicles industry because in our. The thing the students are getting placed in Montreal Electric. There the IT is nothing but EV manufacturing company, EV electric auto rickshaw manufacturing company and all. So especially by studying this power electronics devices like Igpt and MOSFET, they will come into touch with the manufacturing of MOSFET and Igpt everything. So it is very useful for.

The these days and also we'll be having the either and uh or uh, companies are there, they are using these devices and especially we are having this BSS battery energy management system also. So these devices play. Very much role in this kind of things.

Thank you for your explanation. To ensure clarity for your students, how would you structure a practical laboratory session to teach them how to work with and test the characteristics of an IGBT?

Uh, we will be doing the IGPT characteristics lab and all. So I GPT the output characteristics and input characteristics will be doing by the lab and how efficiently it is working with the thing. And similarly for the MOSFET also. We'll be doing both simulation and.

Will be having power electronics lab especially, so we'll be taking the carrot output characteristics and input characteristics.

The practical thing we'll be doing?

Understood. Moving on from Power Electronics, let’s discuss your ability to evaluate students and manage exam duties. Could you provide an example of how you design an assessment or examination for a course, ensuring it evaluates both theoretical and practical knowledge effectively?

Sir, as the power electronics lab in charge, we conduct the experiment as well as we conduct the theory classes. Also in theory classes, we will be teaching the method, how it is operating, how the uh. Working model is there and how the input and output characteristics are there. But in practical lab we will be showing them how it is it and we'll be connecting to the load supply and voltage supply where we'll be getting the output and as well as we'll be doing this simulation for the IGBT how the IT will be working and it is having the IGPT is having the high.

Voltage capacity also and high current also around 600 voltage to six point KV will be getting and it has got the lower conduction losses than MOSFET and high power. It has got a simple gate Dr. also. It is a voltage control device as we know and it is slower switching that mosfets also it is used for high power applications. Very high frequencies It is not very.

So these things will be telling about these things and we will be telling that IGBT's will be using inverters especially solar UPS and industrial drives and MOSFET drives also will be using and it will be using for SMPS, induction, heating, HVDC facts. These things will be using and solar power and all will be making the students go to the our college itself.

Very much ideal.

Now got the solar panels and all we'll be making them to understand by showing the the solar panels over there and they the calculations, everything we'll be doing.

Thank you for providing that context. I appreciate the technical depth in your response. However, could you elaborate on how you specifically evaluate student performance during labs or theory exams? What methods or metrics do you use to ensure a comprehensive assessment?

We'll be making the students understand the objectives and circuit topology and the ability to predict the waveforms, that is VA and gait signals and the we'll be making them to know the knowledge of ratings that is Igpt, MOSFET, voltage, current and power and the safety awareness. Also we will teach that is isolation airthing that time etcetera. And when we are going to test it, we will be having 2-3 oral questions before switching it on and we'll be showing the quick sketch of expected reforms and all. So while implementing the hardware handling they we have to evaluate the correct wiring, whether it is gate load, supply measurement points are correctly given and proper. Use of gate drivers. Weather up to isolation is given and heat sink usage, thermal awareness, everything will be checking and the instrument handling we will be using DSO props, current props etcetera. So the. Gate, emitter, resistor and all, we'll be checking and you'll be seeing whether the charting grounds are corrected, correctly connected, etcetera.

Sir, can you repeat the question? I didn't hear it.

Sir, your voice is breaking.

My question is: Could you describe how you guide students in their research or project work, ensuring they remain focused and achieve meaningful outcomes?

Uh, Sarah, is that your question is how we, I have to, uh, guide the students?

Yes, Professor. I’d like to understand how you guide students in their research or project work to ensure they remain focused and achieve meaningful outcomes. Could you elaborate on your approach?

Uh, we have to start framing the problem, uh, first, uh, not the circuit. So most students straightly jump to, we'll build the inverter or something like that, then get them to answer first what problem we are solving. Then why this problem matters. Efficiency, cost, ripple losses, control everything. We'll see. And we will, uh, whom this system is used for. Solar industry UPS like that we'll be seeing then we'll be we'll be seeing whether it is an IGPT inverter project or something like that and the we have to fix the scope earlier itself how the power electronics projects for mostly due to some some some force clear boundaries should be there how the voltage.

Well example 48 bar 100 voltage it it should be not for 100 voltage DC link for students and all and power level 100 to 500 Watt like that and switching frequency range and if it can be simulated or built test, test the circuit also something if you are making we have to test also then. They make simulation mandatory before the hardware.

Where that should be done for the research project because after doing hardware if it is does not work means it will be problem. So we'll be doing the work in simulation through MATLAB or Simulink or SPICE or Lt. space and we'll be doing non ideal switch modeling also and we'll be predicting waveform prediction. VI gate signal and we'll be seeing the switching losses and conduction. So loss estimation. So we'll be doing and then after that checking the switching characteristics or something like that, we'll be take the device selection. So what device we have to select most for IGBT and what margin of voltage or current we have to see switching speed, everything we have to see then gate driving characteristic. Then gate resistance selection.

Gate voltage levels, uh, then uh, we have to see the how it will should be improved from the previous level and uh, uh, everything we'll be seeing then, uh, as a project guide recommendation also we'll put we'll be putting the problem statement and motivation, then literature review will be conducting then. The simulation results will be evaluating then only we will be doing the hardware setup and.

Results will be checking.

Sir, could you repeat the question because the range is not clear here due to rain.

Certainly, Professor. How do you approach teaching complex theoretical concepts to students, ensuring they understand and connect it to practical applications?

Uh, actually we, we contact the, uh, teaching method not only by, uh, chalkboard, uh, teaching, but uh, with the, uh, uh, projector or, uh, online teaching smart room, It is there. So, uh, we have, by using the smart room, uh, smart board, we can visualize and mathematical applications. Also, if it is a DC motor or synchronous motor or an induction motor, we could see the working.

Sorry

Properly. But before and all earlier days the smart port was not there and we couldn't, we could not see how it works and all. But nowadays due to smart board and visualization is possible also if we are teaching the circuit theory and all, we'll be doing circuit debugging also. So circuit debugging in the sense that we'll be showing half of the circuit and half of the circuit students has to think how it works and all.

And we will be having this kind of things also. And there is another method of teaching the students like flip classroom method also. That means we we will ask the students to prepare one topic before itself and then they will come and see how the classes will be taken for the for their peers. And if we are, we are teaching with the the waveforms and all, it will be very clear while we are using the smart board and. Because we can draw with different colors also switching circuit and output voltage we can do with different colors also and so that students will be easily. Understand also if you are connecting buck boost and all we can do practically and show the simulation also in the classroom itself we can do in laptop or we can do the simulation like how the switch ideal diode.

For RL load how it is connecting and the PWM waveform how it can be given and all so these things we can give the give them by practical implementation also.

Thank you, Professor. You’ve provided a rich overview of your teaching methods, ranging from smart classroom techniques to engaging students with practical applications and flipped classrooms. To conclude our skill evaluation, I’d like to understand your experience with research publications. Could you briefly summarize your contributions to reputed journals and the nature of your research work?

Sir, I have 12 publications in Scopus, so 12 publication in Scopus means I have got 5CI journals also. So I have got umm, uh, this recently I have got publication recent advances in electrical and electronics engineering that is. I have done a publication with solar and wind based renewable energy in. UH, DGS and D stat com and I have got 2 publications in Springer. Springer means multi scale and multidisciplinary modeling that is in the topic of power quality improvement in the industrial drive using FPGA conductor. Then umm, I have got a Springer nature also Levy Uh-based synchronization of microgrid that was I have done in 2024. Then I've done another sci paper like Optimal Control application in Wiley that is Control strategy based energy management in renewable energy grid connected system and I have done 2 conferences recently that is in I triple E So one is cancer detection with VGG 16, another is prediction of vector borne diseases that is.
