Zusammenfassung:The appts. monitors change of input current by using the current sensor and when unloaded operation occurs prevents the operation. This apparatus senses infinitesimal load and operates the microwave oven at a selected time using a timer. It comprises a high-voltage transformer(1), a controller(2), a current sensor(4), a voltage dropping compensator (5), an input voltage detector(6), a comparison block(7), a timer(8), a microprocessor(9).
