microwave oven power supply
 

I picked up a couple of inverter powered microwave ovens at the goodwill and
I was wondering if these power suppies can be used wih tube amps and such.
Also would like schematic data if I could so I could see if I can modify
them for other voltages besides thosed they are designed.

I didn't know such contraptions existed ;) Please post brand name, model
and nameplate information from them to permit a bit of research. Sounds
like a candidate for the quad 807 linear awaiting a power supply...

Cant get to them right now for more data but one is a Sharp and the other a
Panasonic.

i have found that they are regulated and variable to some degree via pwm Old
stle microwaves varied power by varying the duty cycle that the tube was on
over a period of seconds. that is to say if a 705 power was set the tube
would be on full power for 7 seconds out of 10. the inverter style actually
decreases the voltage to the tube. interesting possibilites about for
amplifiers

This may be a daft question, but is Marketing name for the product
"Inverter" ?

Doing a quick search on eBay, several ovens pop up with this name, one
description was "Panasonic Inverter Microwave Oven 1100W" - looks like
a 110V product to me.

I have never heard of a 12 or 24v microwave oven, 1100W at 24v = 45
amps which seems excessive even as a load for a large truck.

7 seconds On and 3 seconds Off for a 1000w oven is an average power of
700w, assuming your chicken will integrate the power (as all good
chickens probably will :)

Conventional microwaves control the power by ON/OFF cycling of
the oven. For example, 1/2 power might be 5 seconds on, 5 seconds off.
The inverter technology controls the actual klystron operating voltage
to set the power level, and the food is heated continously. I'd suspect
the variable power feature has horrendous artifacts on the supply
voltage making it completely unsuitable for use by hams.

yes, there are appaently 2 types, one is made to run off of 12 volts maybe
24 VDC and the other runs off of 120VAC.
I think the 120VAC initially converts it to 300VDC then aplies it to the
inverter circuit.. Still trying to find a schematic to verify. I would think
this technology could be a major help for amp builders allowing us to build
inexpensive power supplies and easily custom wind the inverter transformers.

Uncle Peter has spoken so i guess i shouldjust give up on the idea.

I offered a opinion on Usenet... You can take it for what is worth..
