Abstract

This paper presents a new soft commutation forward converter operating with almost unity power factor. The proposed approach allows building of a converter with high power density and high operation efficiency. Moreover, sinusoidal input current can also be obtained satisfying the IEC555-2 standards. The operating principle, theoretical analysis, relevant equations, simulation and experimental results for the converter are presented
