摘要： A power control unit for high-frequency dielectric heating is provided. The power control includes an input current detection section for detecting input current from an AC power supply to an 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. An input voltage detection section detects input voltage from the AC power supply to the inverter circuit and outputs input voltage waveform information. A selection section selects the input current waveform information or the input voltage waveform information, whichever is larger. The conversion section also converts the selected input current waveform information or input voltage waveform information into the drive signal of the switching transistor of the inverter circuit.

摘要： A power control method for high-frequency dielectric heating is provided. The method includes detecting input current and input voltage from an AC power supply. Input current waveform information and input voltage waveform information are acquired. It is determined whether the magnetron is being oscillated. If so, the input voltage waveform information is added to the input current waveform information until oscillation of the magnetron is detected, and the addition result is converted into the drive signal of a switching transistor of an inverter circuit. If not, the input current waveform, without addition of the input voltage waveform, is converted into the drive signal of the switching transistor of the inverter circuit.

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.
