摘　　要：提出了适用于DC-AC型非接触电能传输(CPT)系统的新型电路拓扑,并采用不对称DC-AC变换器实现了该新型拓扑。该拓扑简化了DC-AC型CPT系统的电路结构,简化了和系统的控制方式,减少了次级回路电能变换的损耗,提高了整体系统的效率和功率密度。介绍了采用该变换器的电路拓扑和控制策略,对采用该变换器后的CPT系统进行了建模,并在此基础上对系统进行仿真研究,给出了实验结果,对分析和仿真结果进行了验证。A new type of circuit topology for DC-AC type contactless power transfer（CPT） system is proposed,and the asymmetric DC-AC convert is used to imply the new topology.The topology simplifies the circuit and control of DC-AC type CPT system,reduces the power loss of power conversion of secondary circuit,and improves the overall efficiency and power density of the system.This paper presents the topology of the converter and investigated its control strategy.A model of the system has been derived,with which the system is simulated and studied.The measured experimental results have verified the theoretical and simulation results.
