摘要
导出了无源软开关电路的最简拓扑条件 ,由此提出一种新型的具有最简拓扑的无源无损软开关技术 ;这是在传统的L +RDC缓冲电路基础上 ,去掉电阻 ,利用附加在变换器中的电感器上的一个耦合绕组 ,以感应电势自举提高吸收暂态能的电容器电势 ,实现无环流下的电容器电能的谐振馈能复位。对该电路进行的理论分析。
A condition of the passive soft switching with the simplest topology is derived So a novel technology of the passive lossless soft switching with the simplest topology is presented,which is on the basis of conventional L+RDC snubber with discarding of the resister It is achieved by using an additional wind magnetically coupled with the inductor of the converter that raises of itself the potential energy of the capacitor applied on getting back the transient energy during transition to finish energy recovery by resonance without producing any current circulation The circuit is analyzed theoretically,simulated with the computer,and experimental results are verified that the technology is applicable
