Abstract
A high frequency heating source provides a predetermined high frequency heating output. An inverter receives an AC input and provides a high frequency output for driving the high frequency heating source. The inverter includes a rectifier for rectifying the AC input and a switching element for switching a DC output from the rectifier. The microprocessor outputs an ON/OFF signal having predetermined ON and OFF periods in accordance with a set output value associated with the high frequency heating output. A driver drives the switching element of the inverter in accordance with the ON/OFF signal output from the microprocessor.
