ABSTRACT:
A high-frequency dielectric heating power control method comprises: detecting the input current of an inverter circuit for rectifying the voltage of an AC power source to convert the rectified voltage into an AC voltage of a predetermined frequency; rectifying the detected current to determine an input current waveform; shaping the waveform to determine a reference waveform; determining the difference between the input current waveform and the reference waveform; and mixing the differential information and the current control output by a mix circuit to convert the mixed one into the drive output of a switching transistor of the inverter circuit.
