I have a microwave oven that is acting up a bit. Seems to not heat as fast as it should. I'm thinking it may have a bad transformer, but how do you measure something that is supposed to be 2KVDC?
The circuit consists of a step-up transformer, a high voltage diode and a high voltage capacitor. I think (I said "I THINK") the diode and capacitor work to double the voltage as well as rectify it. With a positive going sine wave, the capacitor is charged through the diode. When the sine wave goes negative the capacitor adds 1KVDC to the transformer output and makes for a 2KVDC voltage source. (or something like that)
I want to measure it but only have standard measurement tools. And yes, I know enough to be careful around the high voltage AND the capacitor. How would YOU measure the voltage? My standard DVM only measures as high as 600AC volts.
