摘　　要：针对目前无线电能传输系统存在的问题,提出了一种隔直型拓扑并联无线电能传输发射端电路.该传输系统发射端采用隔直型拓扑结构抑制输入端电流冲击和突变,并且通过移相的方式改善输入电流纹波进而提高系统效率、减小系统静耗和电流振荡对电源侧的损耗.通过仿真和实验在不同模式对隔直型与传统并联两种拓扑结构进行理论分析并证明该理论的正确性,最终完成样机制作,在输入电压为12 V、输出功率为28 W的情况下,隔直型拓扑的传输效率达到82%,传统拓扑的传输效率为81%.Aiming at the problems existing in the current radio energy transmission system,a separable radio energy transmission topology parallel shunt transmission circuit is proposed.The transmitter of the transmission system adopts a separate topological structure to suppress the current shock and noise.In order to improve the system efficiency and reduce the system static loss and current oscillation loss on the power side,the input current ripple can be improved by the following methods.In this paper,two topological theories are analyzed.The correctness of the theories is verified by simulation and experiment under static and on-load conditions.It has extensive guiding significance to the design and application of PP wireless power supply field.The prototype was finally completed.The transmission efficiency of the IDC topology and traditional topology reaches 82%and 81%,respectively,with 12V of input voltage and 28W of output power.
