一种利用直流隔直电容为DAB变换器提供更低电感电流的混合调制策略

For the dual active bridge converter, the single phase shift (SPS) modulation strategy is simple and effective for controlling the transmission power. However, when the voltage varies widely, it is hard to realize soft switching and the circulating power increases dramatically, which results in the increased current stress and reduced efficiency. Thus, a hybrid modulation strategy is proposed in t...
