This paper proposes a power-ripple compensation method for a three-phase/single-phase switchable dual active bridge (DAB) matrix converter. The feature of the proposed circuit is utilization of the center tap transformer to achieve Active power decoupling (APD) without additional switches and large-capacitors. Moreover, the proposed circuit maintains a high power-factor even under light-load conditions. Experimental verification using a prototype converter demonstrates 500 W output power at a power factor of 0.99 and an 82% reduction in the power-ripple component.
