Abstract

This study proposes a matrix converter (MC) control method capable of power decoupling (PD) for a single-phase input isolated AC-DC converter. The proposed converter can also be fed by a three-phase source without any additional components. The PD circuit shares its capacitors with the input filters and its switches with the MC, and absorbs the source power ripple to supply a constant DC voltage for the load. Moreover, the MC control method achieves a sinusoidal source current, a high output frequency, and soft switching. Additionally, the feedback control to compensate for the DC output voltage error is applied. The proposed method is evaluated experimentally.
