Abstract
New methods are studied that can suppress EMI noises, especially common mode currents produced in the motor drive system. One is a packaging technique that forms power converters using a four-layer printed power circuit board. The other is a method based on the generation mechanism of common mode currents which was developed from experimental analyses. It is proved by experiments that the former can effectively control common mode currents, including radiated emissions, and the latter can suppress them without any compensators between the inverter and the motor.
