Abstract

Typical boost PFC power converters generate serious common mode interference that is the dominant radiated EMI mechanism. A novel boost converter with an auxiliary anti-phase winding of the boost inductor which exhibits an extraordinary low common mode noise level is presented in this paper. The size and cost of the common mode choke are reduced. A common mode model of the proposed circuit is developed to analyze the effect of noise attenuation, and design issues are discussed. Experimental results show this approach makes a significant contribution to reduce the common mode noise level
