Take a look at

 and
http://www.hot-streamer.com/temp/KCH_TCH5A.jpg
"5" is a new photo like the "4" I previously posted while "5A" is 
waveforms from a simulation I just ran of a basic IGBT H-bridge 
driving the 15 uH/400 nF load that I have in the hardware.  In 5, the 
top waveform represents primary current in my hardware & the bottom 
represents the H-bridge's power-supply current.  In 5A, the green 
waveform represents the load (i.e. primary) current & the blue 
waveform represents the supply current.

Hardware & simulation show essentially the same waveforms, except, in 
the hardware, for a) the fuzz at switching-times, b) an offset from 
the zero line and c) the "squiggle" in the power-supply current about 
1 us after the switching times.

Interesting...what's the squiggle, I wonder?
