Abstract :
In this paper, status and recent research trends related to the EMC issues in the variable speed drive system are first reviewed. The existing remedies are discussed in two parts. They are, passive filtering and active filtering. Their merits and demerits are presented. Based on the present solutions, a new common mode suppression approach is proposed. It is called the fourth leg active filter. The principle and benefit are presented. This approach is verified by simulation.
