一种减少开关损耗的变频控制技术

A Variable-Frequency Control Technique to Reduce Switching Loss

讨论了一种减小反激变换器开关损耗的变频控制技术。该技术使得反激变换器工作在临界的完全能量转换 ( DCM)状态 ,负载可以有较大的变化范围 ;同时也提高了变换器的效率。

A variable-frequency control technique is applied to the flyback converter to reduce converter's switching loss.It makes the flyback transformer working at the boundary of the continuous conduction mode (CCM) and discontinuous conduction mode(DCM) and having a wider range of the load than ever;meawhile the converter's efficiency is improved.
