摘要：
This paper presents a three-phase unidirectional rectifier power-factor correction (PFC) using two modified single-phase Buck rectifiers in continuous conduction mode (CCM). The phase reduction technique using an autotransformer based on Scott Connection renders a non-isolated rectifier to operate with unity power factor. The power autotransformer is only 14% of the total output power. Two single-phase buck rectifier interleaved is able to regulate low voltage output. The control system is simple and it has only one voltage control loop. Theoretical analysis, design procedure, complete simulation results with closed loop operation are given and a 4-kW prototype has been implemented in the laboratory which demonstrated to operate successfully with excellent performance.
