Abstract
A CM noise reduction method by adding a terminal ground filter between the cable ground and chassis is proposed. The noise reduction performance of the terminal ground filter is estimated with a simplified circuit model. The proposed filter is implemented in a small PCB, and applied to a 3.3kW power system of an air conditioner. The reduction of the CM CE noises by applying the terminal ground filter is experimentally validated.
