Embodiment Construction
[0116] The present invention will be described in detail below in conjunction with accompanying drawing and embodiment, have also described technical problem and beneficial effect that technical solution of the present invention solves simultaneously, it should be pointed out that described example is only intended to facilitate the understanding of the present invention, and to It does not have any limiting effect.
[0117] like figure 1 As shown, the dual-active full-bridge bidirectional DC-DC converter disclosed in this embodiment is mainly composed of a main circuit and a control circuit. The main circuit is composed of two full bridges, the middle part is connected by a high-frequency transformer, and the magnetizing inductance is connected in parallel at both ends of the transformer. The leakage inductance of the transformer is used as an energy storage element, which is an interface connecting the energy of the input end and the output end, and is a bidirectional energy...
