Microwave oven |
摘要 |
A microwave oven includes a direct current (DC) power supply unit which supplies DC power to a magnetron so as to suppress noise induced in a high voltage line. The DC power supply unit includes at least one rectifying diode and a choke coil. The rectifying diode rectifies high frequency alternating current (AC) power generated by a heater coil into the DC power to suppress noise induced in the high voltage line of a high voltage transformer. The choke coil forms ripples in the DC power and effectively prevents a moding of the magnetron, which is generated where a constant DC voltage is supplied.
