Question

No. of transformers in the microwave oven is

Answer 1

A typical home microwave transformer has two secondary windings. One winding provides 3.1 to 3.2 volts, while the high voltage winding provides between 1800 - 2800 volts (average ~2200 volts). The low voltage output is used to light the filament in the microwave-generating vacuum tube (called a magnetron). The high voltage AC output from the transformer is changed to DC and doubled using a voltage doubling circuit (diode and HV capacitor) to power the magnetron.A microwave oven transformer and voltagedoubler operate at lethalvoltage and current levels, so don't mess with them unless you know exactly what you are doing. And always treat them with utmost respect.
