Motor Carrier Electromagnetic Noise Caused by PWM Pulse Modifying Technique of DC Bus Current Detection

This paper describes the carrier electromagnetic noise caused by PWM pulse modifying technique of DC bus current detection. It is cleared from theoretical analysis that the influence factors of carrier harmonics are DC voltage, self-inductance and pulse modifying width. As estimated the carrier elec...
