The Dual-Active-Bridge is a promising isolated, bidirectional DC/DC converter topology, particularly suitable for applications where high efficiency, galvanic isolation and large voltage conversion ratios are required. However, in low voltage, high current applications, the low voltage current ripple may be considerably high, thus requiring large capacitive filtering. As an alternative to the standard Dual Active Bridge, the Active Bridge Active Clamp (ABAC) converter is introduced in this paper. The ABAC converter overcomes the current ripple limitation by directly imposing the load current. Conventional Phase Shift modulation is adapted and analyzed for the ABAC converter. In order to optimize the operation of the topology, a Ripple Cancellation Phase Shift scheme is investigated. Finally, experiment results from a 10kW ABAC converter are presented to validate the theoretical claims.
