摘要
提出了一种无线电能传输最大效率恒压输出技术,该技术采用半控整流电路替代接收回路常用的二极管整流电路,并利用Boost电路调节输出电压。通过同时在线调节半控整流电路和Boost电路的占空比,实现系统在负载和耦合线圈间互感变化时保持最大效率下的恒压输出。实验结果验证了所提技术的可行性和理论分析的正确性。
This paper proposed a technique of maximum efficiency and constant voltage output for wireless power transfer system.A semi-bridge rectifier is used to replace the common diode rectifier on the receiver side,and a Boost circuit is adopted to regulate the system output voltage.The duty cycles of the semi-bridge rectifier and the Boost circuit are online adjusted so that the wireless power transfer system can keep both maximum efficiency and constant voltage output when load varies and mutual inductance of coupled coils changes.Experimental results verified the feasibility of the proposed technique and the correctness of the theoretical analysis.
