Abstract
A power control unit for high-frequency dielectric heating is provided. The power control unit controls an inverter circuit for rectifying voltage of an AC power supply, and modulates the on time of a switching transistor during high frequency switching. The power control unit includes an input current detection section for detecting input current from the AC power supply to the inverter circuit and outputting input current waveform information. A conversion section is provided for converting the input current waveform information into a drive signal of the switching transistor of the inverter circuit so that an instantaneous fluctuation of the input current waveform information is suppressed.
