| 摘 要： | 在松耦合感应电能传输（LCIPT）系统中，系统工作频率大小的选择与电源的成本和系统电能传输大小有密切关系，限于目前功率电子器件水平和系统效率要求，提高系统频率受到限制．介绍了一种变换器拓扑结构，利用LC振荡时传输电能，当电容电压衰减到设定值时闭合开关对电容充电，使得开关管频率远小于谐振频率，从而提高了系统工作频率，降低了系统成本；最后，用Saber的时域和频域仿真验证了其正确性。该拓扑结构不仅适用于LCIPT，对于其它的变换器结构同样适用．

| Abstract: | In LCIPT system, the selection of system operation frequency has a relationshi Pwith the cost and power transfer capability of the power supply. Due to the development of Power device and system efficiency requirement , it is restricted to increase the system operation frequency . This paper presentes a topology which transfers power through LC oscillation. When the voltage of the capacitor is less than reference voltage, the switch is turned off and the capacitor is charged, which makes the switching frequency far less than the syntonic frequency. Thus the system efficiency is improved, and the system cost is reduced. This is verified by the time domain and frequency domain simulations of Saber. This topology not only can be used in LCIPT, but also in other convertors. |
