摘要: A system for reducing Radio Frequency Interference (RFI) produced by motors which are powered by Pulse Width Modulation (PWM). It is believed that the PWM induces radiation at the PWM frequency and harmonics. The invention shields power cables which carry the PWM pulsed current, and provides capacitive shunting of one of the cables to ground.
