A DCM Single-Controlled Three-Phase SEPIC-Type Rectifier

A discontinuous conduction mode (DCM) three-phase single-ended primary-inductor converter (SEPIC) is presented in this article. The analyzed operates as a high-power factor stage AC–DC conversion systems. As its main features, it presents three controlled switches and single control signal with simple implementation low-current harmonic distortion. topology, design equations, operation modes are well simulation analysis considering 3 kW–220 V input to 400 DC output converter. experimental results included, an application the rectifier low-power wind energy systems (WECS) based on 1 kW permanent magnet synchronous generator (PMSG) variable voltage frequencies. From performed paper revealed, concluded that indicated be employed any system, such distribution systems, distributed generation or hybrid containing variable-frequency generation.
