Abstract :
This paper proposes a novel control scheme for a dual active bridge (DAB) DC/DC converter. The proposed control scheme eliminates the large feedback energy problem existing in previous DAB converters and achieves ZVZCS of all switches. The efficiency and output capacitor current ripple are improved. Simulation results and experimental results from a prototype are presented
