POWER CONTROLLER OF MICROWAVE OVEN AND POWER CONTROL METHOD

摘要

PURPOSE: A power controller of microwave oven is provided to improve a reliance of a product by controlling inrush relay with a stable signal. CONSTITUTION: The power controller of microwave oven having a power supply(1), magnetron(10) for generating a electric wave and a high voltage transformer(9) comprises: an inrush relay(21) arranged between the power supply(1) and the high voltage transformer(9); an inrush resistor(23) connected to the inrush relay(21); a rectifier(8) rectifying a power supplied from the power supply(1); and a relay coil(15) generating induction power with current rectified by the rectifier(8), thereby driving the inrush relay(21).
