An active circuit for cancellation of common-mode voltage generated by a PWM inverter.

Presents a study which used a pulsewidth modulation (PWM) inverter to develop an active common-noise canceler (ACC) capable of eliminating the common-mode voltaged. What is incorporated in the ACC; Use of experiment to verify the ACC veribility and effectiveness in eliminating common-mode voltage in a 3.7-kW induction motor drive; What some experimental results show.
