提出了一种新的双有源桥式变流器的调制策略。新策略的目标是通过最小化负载角来抑制变流器中的环流。采用频率变化和相移调制相结合的方法，扩大了软开关的工作范围。与已有的基于频率变化的调制方法不同，本文提出的策略可以在轻功率或大功率传输下工作，而不受频率限制和电压比的限制。实验证明，与传统的单相移法相比，新策略的整体效率提高了7%。
This paper proposes a new modulation strategy for a dual-active-bridge converter. The target of the new strategy is to suppress the circulating current in the converter by minimizing the load angle. The soft-switching operational area is expanded by employing frequency variation together with phase shift modulation. Unlike published modulation methods based on frequency variation, the strategy proposed in this paper can operate under the light or heavy power transmission regardless of the frequency limitation as well as the voltage ratio. As confirmed by experiments, the new strategy can boost the overall efficiency by up to 7% compared to the conventional single-phase-shift method.
