要約(日本語): The dual-active-bridge (DAB) topology is ideally suited for high-power galvanically isolated dc/dc conversion. It has advantages of high power density, zero-voltage switching (ZVS), bidirectional power transfer capability, a modular and symmetric structure, and simple control requirements. However, for applications requiring wide voltage variations, such as interface for energy storage, fuel cells, or photovoltaics, the DAB has problems in maintaining high efficiency.This is due to limited ZVS range and high circulating currents at low loads. The phase-shift control (PSC) and single phase modulation control (SPMC) is used to overcome these problem.
