This paper proposes an active power decoupling method using a Dual Active Bridge (DAB) converter without additional components for single-phase isolated AC/DC converter applications. The proposed power decoupling adjusts the phase difference between the primary and the secondary transformer voltage against the power ripple with twice the grid frequency. Experimental results show the validity of the proposed method. As an experimental result, the second harmonic component in DC voltage was reduced by 91.2%, owing to the proposed power decoupling control without the bulky electrolytic capacitor.
