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. Jimmie |

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... Regards, Michael |

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 -Mark On Jul 28, 8:15 am, "Jimmie D" wrote: "Jimmie D" wrote in message ... "msg" wrote in message ...

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.

Jimmie 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. |

It might just need additional filtering if they are using some sort of pulse width control of the klystron duty cycle. I was just expressing an opinion. My kitchen microwave is a Panasonic inverter type. Pete |
