Isolated and Bidirectional Three-phase Single- Stage Quad-Active-Bridge Series-Resonant ACDC converter

Abstract

A novel isolated and bidirectional single-stage three-phase AC-DC converter called Quad-Active-Bridge Series-Resonant (QABSR) ACDC converter is proposed. Unipolar voltages

switches are used to modulate the grid voltages. The proposed modulation allows to obtain minimum HF current and a decoupled grid current control. Converter design, simulation and experimental results are presented.
