Abstract

This paper presents a three-phase rectifier, unity power factor, nondissipative commutation in DC-DC converter and synchronized frequency control, working with 89% of global efficiency and low level RFI. The proposed structure allows the operation with high switching frequency. The output voltage is controlled by PWM with a constant frequency. The operation principle, theoretical analysis from DC converter, relevant equations, current balance control technique and experience results, are also showed in this paper
