摘要
该文明确了控制型软开关的定义,总结和归纳出控制型软开关的 5 个特征。然后用现有的控制型软开关变换器检验了这 5 个特征理论。接着应用 5 个特征理论推导和构造出Buck、Boost、Buck-boost、Cuk、Zeta、Sepic、Flyback、Forward等一系列拓扑的控制型软开关的实现方法。一个 48V 输入,19V/5A 输出,开关频率为 200KHz 的同步 Buck 变换器样机进一步验证了控制型软开关 5 个特征理论的正确性,其满载效率达到了 96.1%
Paper clears up the definition of control type soft switching and presents five characteristics for control type soft switching. The theory of five characteristics is verified in the existing control type soft switching topologies. And a series of new control type soft switching topologies, such as Buck, Boost, Buck-boost, Cuk, Zeta, Sepic, Flyback, and Forward are constructed by using the theory of five characteristics. A 200kHz prototype of 48V input, 19V output, whose conversion efficiency is 96.1% is built to further verify the theory of five characters for control type soft switching.
