摘要： A high-frequency dielectric heating device includes: a microwave output unit including an inverter unit using a semiconductor switching element, heat-radiating fins for radiating the heat generated by an IGBT, and a printed board having a thermistor for detecting the temperature of the semiconductor switching element, The thermistor is soldered to a leg portion of the semiconductor switching element or near to the leg portion thereof on the side of the soldering surface of the printed board. The device also includes: a booster transformer, a high-voltage rectifier unit, and a magnetron; and a heat-cooking chamber fed with microwaves radiated from the magnetron. When the thermistor has assumed a predetermined resistance, a power-down control operation is effected by greatly decreasing the power fed to the semiconductor switching element. Then, permitting the power fed to the semiconductor switching element to vary depending upon the resistance of the thermistor.

摘要： A power control unit for high-frequency dielectric heating is provided, and 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 converts the input current waveform information into a drive signal of the switching transistor of the inverter circuit so that instantaneous fluctuation of the input current waveform information is suppressed. A mix circuit mixes the input current waveform information and power control information for controlling so that current or voltage at an arbitrary point of the inverter circuit becomes a predetermined value and generates an on voltage signal. The conversion section converts the on voltage signal into the drive signal so that the on time is shortened in the portion where the input current is large and that the on time is prolonged in the portion where the input current is small.
