This paper presents the operation of a three phase rectifier, unity power factor, non dissipative commutation in the DC-DC conversion and control synchronized in frequency, working with 89% of global efficiency with low level of EMI. The structure proposal allows the operation with high switching frequency. The output voltage controlled by PWM with a constant frequency. The operational principle, theoretical analysis of the DC conversion, relevant equations, control technique for the current balance, experimental results are shown in this paper.
