7.1. Variable power cooking control
The HIGH VOLTAGE INVERTER POWER SUPPLY controls the output power by a signal from the
digital Programmer circuit DPC. The power relay (RY1) turns on to supply power to the inverter
circuit. The level of output power is controlled by the drive signal level from the inverter circuit.
NOTE1: The ON/OFF time ratio does not correspond with the percentage of microwave power
since approximately 2 seconds are required for heating the magnetron filament. / NOTE: 2 If
microwave cooking is over 8 minutes on HIGH power, the fan motor rotates for 1 minute after
cooking to cool the oven and electrical components.
