Common mode current attenuation techniques for use with PWM drives.

The most common modulation strategy adopted for motor control in adjustable speed drives (ASDs) is pulse width modulation (PWM). In general, the output is modulated at a carrier frequency ranging from 1.0 kHz to 20.0 kHz. Experiences with PWM drives have shown that there exist two important concerns...
