Coursera | Power Electronics Specialization

Coursera has a good one

Hey, i work leading a team of e-machine simulation engineers, with focus on control and some power electronics simulations (also thermal integration, vibrations, etc.). I honestly do not know any good courses about all these things combined, but Universiy of Colorado Boulder has quite nice ones about Power Electronics from what my teammates told me (https://www.coursera.org/specializations/modeling-and-control-of-power-electronics and https://www.coursera.org/specializations/power-electronics). As for electric machines, this is the best I have found, also from the same university (https://www.coursera.org/learn/motors-circuits-design). Hope this helps!

I think perfecting PCB design will be crucial to you in the future. Also, as a power electronics major, knowing how to design magnetics (inductors and transformers) is really important. I would recommend you start by taking power electronics courses in coursera by Dr. Robert Erickson. It is a series of four courses that will help you get a deeper understanding of power electronics. You probably already understand the first one but the next three are useful.

The questions you are asking are great questions, but require quite a bit of background that would take too long to explain. Also troubleshooting with only a multimeter will make this substantially harder if not impossible.

One of the reasons you are getting only about 50V out is because after that you'll start to get swamped with losses. You probably will need the turns ratio of a transformer to get the output you want.

Moving into transformer based designs, you can create very high voltages quite easily. Please be careful that you don't hurt yourself.

If you want to learn about power electronics specifically, Coursera has a course on it from UC Boulder. It does assume some circuit knowledge, though.
