摘要:
A power control unit for a high-frequency dielectric heating not affected by variations in the magnetron type or characteristic, and power supply voltage fluctuation, etc., is provided. The power control unit for a high-frequency dielectric heating has an input current detection section 71, 72 for detecting input current of an inverter 10 for rectifying 31 an AC power supply voltage 20, performing high-frequency switching of the voltage, and converting the voltage to high-frequency power. The power control unit for a high-frequency dielectric heating converts a switching frequency control signal 92 provided by mixing input current waveform information 90 and power control information 91 into a drive signal of a semiconductor switching element 3, 4 of the inverter.
