传统的无线电能传输系统需要同时在发射端和接受端串联或并联电容来补偿线圈间的漏感，从而提高系统的传输效率。一旦电容器发生故障或者随温度变化发生改变，系统就会失谐，导致传输效率降低。文章针对这一弊端提出单端补偿的新型无线电能传输系统，其接受端采用 PWM 可控整流，与传统的二极管不控整流相比，可以通过移相控制来调节输出功率。通过在不同移相角的仿真结果和5 kW的实验平台，验证了理论分析的正确性和控制策略的有效性。

Traditional wireless power transmission system requires capacitors in series or parallel with both the trans-mitter and the receiving side to compensate for leakage inductance between the coils,thereby improving the transmission ef-ficiency.Once the capacitor fails or changes with temperature,the resonant tank will be detuned,resulting in lower trans-mission efficiency.To solve the problem,we propose a novel transmission system which is compensated at single side. Compared with the traditional system with non-controlled rectifier,the system uses PWM controlled rectifier at receiving side to regulate the output power by phase shift control.Simulation results under different phase angles and 5 kW experi-mental platform confirm the validity of theoretical analysis and control strategy.
