摘要：
A bidirectional push-pull/H-bridge DC/DC converter for a low-voltage energy storage system is proposed in this paper. It comprises the push-pull converter, the phase-shifted H-bridge converter, and the transformer. The push-pull converter is connected to the low-voltage side, and it is controlled by 0.5 fixed duty ratio. The phase-shifted H-bridge converter is connected to the high-voltage side, and it is controlled by an extended phase shift scheme with zero voltage switching (ZVS). Compared with the conventional dual active bridge (DAB) DC/DC converter, the proposed converter has a simple structure-there are only two power switches with a common ground and simple gate-driving circuits in the low-voltage side. The 600-W laboratory prototype was developed to confirm the theoretical analysis and the validity of the proposed converter. A bidirectional push-pull/H-bridge DC/DC converter for a low-voltage energy storage system is proposed in this paper. It comprises the push-pull converter, the phase-shifted H-bridge converter, and the transformer. image
