Abstract

A microwave oven comprising a magnetron for generating a high frequency in response to a high voltage, a transformer having primary and secondary coils, the transformer generating the high voltage in a turn ratio of the primary and secondary coils and supplying it to the magnetron, and high-power output switching means for controlling the level of a voltage applied to the primary coil of the transformer. The microwave oven with the high-power output switching means can control its maximum power output level on the basis of an allowable amount of current supplied to a distribution board.
