智能电力操作电源及其控制技术的研究

A Research of Intelligent Electric Operating Power Supply and Its Control Strategy

提出了有限双极性的软开关控制策略,研究其控制机理,从理论上解决了全桥功率变换器的传统软开关控制策略存在的软开关受负载限制的缺陷,实现了全负载范围的软开关,降低了电力操作电源系统的损耗,提高了模块的功率密度.

The limited double-pole soft-switching control scheme is presented in this paper, this scheme overcomes the. disadvantages theoretically that the range of soft switching is limited when the load current is less than a special value in the convenient full- bridge soft-switching schemes, and realizes the soft switching function with all of the loads so as to reduce the energy loss and improve the power density.
