Default microwave oven inverter P.S. revisited


THESE MUST BE OPERATED UNDER LOAD OR THEY WILL SMOKE.

At least that is what happend to mine.

Oh, sorry to hear that. Yeah, it's a bad idea to operate
any switch mode power supply without a minimum load unless
the min. load is built-in or the thing is so inefficent that
its own losses make up the minimum load. The output diodes
probably didn't like that... just my guess.

I found some interesting stuff on the panasonic inverter.

On the fusor chat they claim it's 85% efficient and good for
1200W. The efficiency seems right, the 1200W seems... optimistic.

Also this, instructions on getting the inverter to play.
