Steve is correct! I apologize.
If you have a square wave of minimum peak to peak value of zero volts,
its maximum peak to peak value must be 1.414 x the d-c value. Then,
1.414 Vd-c x 1.414 Id-c = 2 Pd-c.
2 Pd-c x 1/2 t = Pd-c for an average.

Whew! Richard H.
For some reason, the above post does not show on my reader. I had to go
to Google to see what I was missing. After seeing your answer to my teaser
about voltage vs. power dB, I was really getting worried (about U) on this
one. You DO know. I think the thing here is that BOTH power and Current
are averaged by the chopper. I am, however, surprised that you did not have
a "gut feel" for that.
I just posted another short explanation of MY take on the term "loss-less
resistance".
I wonder why I am not seeing some posts..
There is another thread about the maximum power transfer theorm. This
thread was about the term "loss less resistance".
