This is very interesting and cannot happen fast enough, considering the current worldwide transformer shortage.
I have a question for people more familiar with these. What exactly happens at the isolation stage. They say it includes a high frequency transformer (HFT). But its input and out put is DC. And classic transformers operate on AC. So in order to get the transformer working, one would have to chop up the incoming dc power into a square wave or a sine wave. But what transistors can you use to do this, considering you are dealing both with very high power and very high frequencies?
