Abstract :
This paper presents a theoretical analysis of the "active circuitry" for a common-mode (CM) transformer to cancel CM voltages. The design methodology, and the practical Implementation issues are presented for motor drive systems rated 460 V or higher. An implementation example and experimental results for a 460-V motor drive system illustrate the feasibility of the proposed ideas.
