A new integrated inductor with balanced switching technique for common mode EMI reduction in high step-up DC/DC converter

Abstract

This paper proposes a new integrated inductor with balanced switching technique applied for high step-up converter. The advantage of the proposed converter is the reduction of the common mode conducted EMI using balanced switching technique. This step-up converter requires more magnetic components than that of the conventional converter. Therefore, the integrated magnetic technique is proposed to reduce two separated coupled inductors into a single core inductor. Finally, the good feature of proposed converter, by reducing common mode conducted EMI with small amount of inductors, is confirmed by the experimental results of a 50 W converter.
