一种基于自然瞬态行为的DAB双级DC-DC变换器控制理论

Combining buck, boost, or buck-boost stages, the dual-active-bridge (DAB)-based two-stage dc–dc converter is regarded as a promising solution for high-power electric vehicle (EV) charging, where wide voltage range is required. However, the design of the control system becomes more complicated because of the power coupling between the two stages. Therefore, a natural transient-behavior-based contro...
