Abstract :
In this paper, the enhancement of operational amplifier gain-bandwidth product used in common-mode (CM) active EMI filter compensation circuit is proposed. The design procedures of CM active EMI filter with current and voltage cancelling compensation circuits are also provided. Finally, the conducted EMI reduction performances of the proposed approaches are compared and verified experimentally.
