An Active Power Decoupling Method for Single Phase DC/AC DAB Converters [PDF]
IEEE Access, 2019 The existence of the double grid frequency (100 Hz) ripple current in dc/ac dual active bridge (DAB) power converters can degrade their performance and as such these ripples need to be compensated. An active power decoupling method is proposed in this paper to attenuate the 100-Hz current ripple in single phase dc/ac DAB converters.
