The three-phase bidirectional isolated dc-dc converter (3P-BIDC) is promising for high power density applications. However, it is challenging to maintain the overall efficiency of the 3P-BIDC over a wide operating power range. The research aims to design and characterize a 150-V, 1.5kW, 20kHz 3P-BIDC. It also aims to combine phase-shift and burst-mode switching to improve efficiency of the 3P-BIDC in light-load conditions (< 30% of the rated power). In medium to high loads, only phase-shift modulation is employed. The paper presents the simulation and experimental verifications of the 3P-BIDC. The paper also investigates the characteristics of the 3P-BIDC using different transformer configurations such as Wye-wye, Wye-delta, Delta-wye and Delta-delta, when operated using the proposed enhanced switching strategy.
