摘　　要：本文介绍了全桥串联谐振软开关技术的工作原理,结合课题详细分析了电流断续工作方式时的四种工作模态,并进行了数学分析。利用工程算法计算了谐振电感值和谐振电容值。实验结果表明,选择合适的电感值和电容值,并且控制开并器件的关断时间可以实现零电流关断。This text introduced the work principle of the Full Bridge Converter That is based on the Series Resonation and Soft Switching Technique, Combining the topic, Analyzing four kinds of molds in detail and carrying on mathematics analysis to it. Using of the engineering calculate way, computing the value of the Resonation Inductance and the value of the Resonation Capacity. The testing result show that choosing the proper value of the inductance and capacity, and that controlling the turning-off time, Turning-off realized under Zero-current.
