Microwave oven in which rush current to high voltage transformer is suppressed
When power supply to a high voltage transformer starts, the phase &thgr; of the voltage of an AC power source when power supply to the high voltage transformer is stopped last time is referred to. In accordance with the value of the phase &thgr;, the phase of the voltage of the AC power source when power supply to the high voltage transformer starts is determined, so that the peak value of the rush current in the high voltage transformer is minimized.
