摘要
功率谐振变换器是一种基于软开关技术的电力电子变换装置。本文从拓扑结构、开关特性和控制技术等不同角度出发,讨论了谐振变换器的基本结构、特点及运行规律,并且提出了相关的应用领域和今后的发展方向。
This article summarizes latest research progress in the development of power resonant converter. The topologies, characteristics and basic operating principles are given in detail. Three resonant converters, i.e. SRC, PRC and SPRC are discussed as the typical topologies and the relevant applications are also involved. In addition, the operating behavior under leading mode and lagging mode is stated. It is suggested that the converter be preferred to operate in the leading mode since it obtains more advantages over the counterpart. As for the control scheme, the principles of variable- frequency control and phase- shift control are presented. Finally, the development tendency of power resonant converter is also prospected.
