Abstract

An EMC analysis of a switched mode power supply (SMPS) have been usually using unbalance circuit topologies and the major factor of disturbance is parasitic capacitance. We have proposed a balanced switching converter circuit, which is an effective way to reduce the common mode conducted noise. In this paper presents the relationship between common mode current and radiated field.
