摘要： An inverter controller controls an inverter. The inverter converts direct current into alternating current of a predetermined frequency. The inverter includes a resonance circuit for fluctuating output of a predetermined object to be controlled. The inverter controller comprises an output fluctuating unit which fluctuates output of the inverter in response to an output value of a temperature detection section which detects a temperature of a switching element of the inverter. The inverter controller further comprises an output increase suppressing unit which suppresses an increase in the output of the inverter for a predetermined time after decrease control in the output of the inverter performed by the output fluctuating unit.

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.
