摘　　要：文章根据控制型软开关半桥DC/DC变换器的定义,总结和归纳了4种控制型软开关半桥DC/DC变换器的PWM控制策略和缓冲型软开关半桥DC/DC变换器对称PWM控制策略。对上述PWM控制策略进行了深入分析和综合比较,为选择具体应用场合提供了依据。According to the definition of control-type soft-switching half-bridge DC/DC converters,this paper concludes and summarizes four types of PWM control schemes for control-type soft-switching half-bridge DC/DC converters and two types of symmetrical PWM control schemes for buffer-type soft-switching half-bridge DC/DC converters.Analyses and comprehensive compares are taken between the above PWM control schemes to provide the basis for choosing specific applicationgs.
