In the end we have made a 50v / 10a full - bridge pwm dc / dc converters based on an improved circuit topology of full bridge phase shift zvs pwm converter . it can achieve zvs from no load to full load in virtue of an assistant commutation inductor 最后，构造了一个改进的全桥移相zvsdc dc变换器拓扑，在此基础上研制了50v 10a通讯用全桥移相开关电源，该电源借助于辅助换流电感，在空载到额定负载范围内均可实现zvs 。
