Hello Aksshay,

Regarding the kits, The coronavirus situation is expected to disrupt shipping for a long time. So we will update you on this once we can get a better idea of the timeline.

3 - The course is going to be application and practical based so we will design converters from off the shelf components and also layout a PCB in one of the design examples, the software could be Altium or even EasyEDA since it is free. Most of the designs will be based on real-life applications, like making a converter for an EV subsystem or so. It would also involve the process of selecting parts for a converter.

4. - Yes, this can be done.

1.   Does your selected EV have on-board charge-
         - Yes, It has On-Board Charger
2.   What is the rated AC input voltage of the on-board charger?
        -  Level II rated  AC input voltage is 240 V
3.   What is the DC output voltage of the on-board charger?
         - DC output voltage of the on-board charger is 404V
4.   What is the Battery pack nominal voltage?
        - Battery Pack Nominal Voltage is 356 Volts
5.   What type of motor is connected?
        - Permanent Magnet Synchronous Motor
6.   Is there an inverter needed in the drive unit?
       - Yes, the inverter unit is needed in the drive unit
7.   Is there a high voltage DC-DC converter on-board the vehicle?
       - Yes, there is high voltage converter on board the vehicle.
8.   What type of cooling methodology is used? - Passive air, active air, active liquid?
       - Based on the coolant Pump unit & tube lines it shown in picture, It is having active  liquid cooling system
9.   Any other interesting observations you'd like to share?
       - The interesting fact is like that Motor Controller Unit is Packaged below On Board Charger Unit as well as DC to DC converter is packaged vertically. So, overall packaging of
          On- board charger, DC to DC converter & Motor controller drive unit has been packaged in compact way.

Hello MakerMax Inc,

As the Power Electronics Q/A forum is not open, I am asking these questions here.

1) Just as in the EV Foundations and Battery Masterclass courses we were provided the option of choosing test kits or a project; will this Power Electronics course also include test kits which you will provide? 

2) Also if this course includes kits then when can they be shipped given the Coronavirus lockdowns in effect?

3) Can you please elaborate on what exactly the topic 'Designing Real Life Converters from scratch' will cover? Like for example, will it involve the use of Altium software or just normal topology descriptions?

4) There are some jobs available in the Power Electronics space but most of them require 3-10 years of experience and not for entry level or fresher students. I know this is not the part of course curriculum, but if possible will you prepare/suggest us of some questions asked to a Power Electronics engineer in Job Interviews.

Eagerly waiting for a reply.

Thanking you,
Aksshay Sharma
