[Amps] panasonic inverter TSPA

[John T. M. Lyles]

VK3HZ posted some very interesting info in his report on the 
'teardown' of a Panasonic inverter power supply. Cooking magnetrons 
don't like constant voltage power supplies, or regulated voltage, and 
some industrial systems use Current regulation. 100 or 120 Hz ripple 
doesn't mind, as a matter of fact, it is somewhat desirable as it 
causes some frequency and mode variation, so i was told.

Beside the fact that testing anything on the primary side of the 
output transformer means working with a hot chassis, it looks to be a 
really inexpensive way to make HV for the ovens. That translates to 
lower cost and less weight, lower cost shipping, etc.
