【Abstract】 On the occasions of monolithic microcomputer and contactors are packed in one case, electromagnetic interferences, yielded by contactor coils as they are switched on or off, and spark interferences, generated by the pushbutton switches that control contactor coils as they are switched on or off, all make monolithic microcomputer application system work improperly. The article introduces inhibiting methods such as phase splitting, TVP, resistive and capacitive absorbing, time delay and coupling removing.更多还原
