That's not Artur's point zero.

you still see a fet as a digital device, read my post #91, and simple read it entirely. What Artur means is that if you don't change your point of view on digital/analog, he sees no point in discussing the efficiency of a controller with you.

IF you keep seeing a fet/transistor as a digital device (OFF/ON) there is no such thing as losses due to the the constant changing of 0 to 1 to 0 to 1..

just read post #91, it should explain.
