Abstract
After starting the input of a switching signal to a booster circuit whose boosting rate is changeable in accordance with the duty ratio of the inputted switching signal and calculating the output power of an inverter circuit, which is connected to the subsequent stage of the booster circuit, from the output current of the inverter circuit, the target voltage after boosting by the booster circuit is obtained based on the output power. If the actual output voltage of the booster circuit is lower than the target voltage, the duty ratio of the above switching signal is increased, and if higher, the duty ratio of the above switching signal is decreased.
