摘　　要：针对传统感应耦合式电源存在体积大、成本高、效率低等缺点,以及存在原边感应线圈与副边感应线圈分离,使输出电压难以快速稳定等问题,本研究采用基于副边反馈信号联合变频+变占空比的控制方法,提出了一种单管感应耦合式电源,给出了单管ICPT系统结构,分析了该电源的谐振网络,同时对所提电源设计了一种无线反馈系统,为了验证设计的正确性,采用Saber仿真软件对ICPT系统进行仿真和电路实验。仿真实验结果表明,所提出的新型单管感应耦合式电源能够满足输出功率为1kW的设计要求,与传统的感应耦合式电源相比,体积小、成本低、效率高,而且采取基于副边反馈信号联合精准的变频+变占空比的控制方法,实现了输出电压的快速稳定。该研究对全桥和半桥感应耦合式电能传输电源具有一定的参考价值。The traditional inductive coupling power supply has many shortcomings, such as large volume, high cost, low efficiency, etc. It is difficult to stabilize the output voltage quickly because the primary and secondary induction coils are separated. A single switch Inductive Coupled Power Transfer power supply using the control method based on the secondary side feedback signal combined PFMq-PWM was proposed in this paper. It gave the structure of single switch ICPT power supply system, the analysis of the reso- nant coupled network and the design of a wireless feedback system of single switch ICPT system. In order to verify the correctness of the design, the saber was used for ICPT system simulation and circuit experi- ment. Results show that the proposed new single switch ICPT power supply was able to meet the output power of 1 kW design requirements. Compared with conventional induction coupled power, the new single switch ICPT power supply has small size, low cost and high efficiency. Besides, it used precise PFM-c PWM control method based on the secondary side feedback signal to achieve a stable output voltage quick- ly. The study has certain reference value for the full-bridge and half-bridge ICPT power supply.
