INRUSH CURRENT REMOVING DEVICE FOR MICROWAVE OVEN

摘要

PURPOSE: An inrush current removing device for a microwave oven is provided to remove the inrush current generated in the microwave oven when putting in the first power supply. CONSTITUTION: The inrush current removing device is composed of:a rectifying unit(100) to rectify the A.C. flowing on a first coil of a high voltage transformer to the D.C.; an inrush current removing unit(110) driven by D.C. of the low voltage passing through the rectifying unit and to remove the inrush current generated by the high voltage transformer; a resistance(R10) to decompress the voltage flowing on the first coil of the high voltage transformer; diodes(D10, D11, D12) to pass the current passing through the resistance toward one direction and to rectify; a condenser(C10) to charge and discharge the voltage input after passing through the diodes; an inrush coil(11) driven by the D.C. of the low voltage passing through the rectifying unit; and an inrush switch(112) turned on and off by the driving of the inrush coil. Thereby, the power consumption and the producing cost are decreased.
