摘　　要：针对无线电能传输系统充电过程中负载动态变化时,引起系统传输效率和输出电压不稳定的问题,提出了一种结合DC-DC变换器技术的自切换恒压复合型无线电能传输系统.首先,分别对双边LCC和S-S型补偿进行拓扑分析,得出适用于两种补偿的开关频率;然后,提出了基于副边Boost电路控制的恒压策略,并建立了仿真模型证明策略的合理性;最后,构建试验台架,验证了理论的正确性.仿真及实验证明在负载变化下,该系统能保持稳压输出,且系统整体传输效率更加优良.Aiming at the problem of unstable system transmission efficiency and output voltage caused by the dynamic change of the load during the charging process of the wireless energy transmission system,a transmission system of self-switching constant-voltage composite wireless energy combined with DC-DC converter technology is proposed in this paper.Firstly,the topology analysis of bilateral LCC and the compensation of S-S type is carried out respectively to derive the switching frequency applicable to the two types of compensation.Then,a constant voltage strategy based on the vice-side Boost circuit control is proposed.Moreover,a simulation model is built to prove the reasonableness of the strategy.Finally,a test bench is constructed to verify the correctness of the theory.The simulations and experiments prove that the system can maintain the regulated voltage output under load variation,and the overall transmission efficiency of the system is more excellent.
