摘要在感应式无线电能传输系统的实际应用中,通常需要系统输出电压保持恒定。采用一种基于串并/串(SP/S)谐振补偿的感应式无线电能传输系统拓扑结构,当系统发射端和接收端的相对位置确定并采用定频控制时,该结构在全负载范围内具备接收端输出恒压特性。同时分析了随着横向偏移的变化,系统输出恒压增益的变化特性。最后,设计了一个6.6 kW、20 kHz定频控制的感应式无线电能传输实验系统,验证了所采用的SP/S谐振补偿拓扑结构的可行性和有效性。

Abstract：In practical applications of the inductive power transfer (IPT)system,the constant output voltage is typically required.In this paper,the series-parallel/series (SP/S)compensation resonant topology is adopted for the IPT system.With the fixed frequency driving and no changing distance between the transmitting and receiving terminal,the output voltage can maintain constant under full load range.In addition,the changing characteristics of the output constant voltage gain is also discussed with the horizontal misalignment.Finally,a 6.6 kW WPT system with 20kHz fixed frequency is setup to verify the feasibility and effectiveness of the adopted SP/S compensation resonant topology.

Key words： Inductive power transfer series parallel/series (SP/S) fixed frequency constant voltage
