基于T-Π复合谐振网络的恒压型电场耦合无线电能传输系统
An Electric-Field Coupled Power Transfer System with Constant Voltage Output Based on T-Π Mixed Resonant Circuit
摘要
Abstract
Electric-field coupled power transfer (ECPT) systems employ high frequency electric field as energy medium to transfer power wirelessly. In practical applications, a lot of electrical equipment requires a constant input voltage for stable operation. An ECPT system with a constant output voltage based on a T-Π mixed resonant circuit is proposed in this paper. The system output voltage is kept at constant regardless of variations in the load resistance without any extra detecting or regulating circuits. Meanwhile, a zero-phase-angel state can be maintained all the time. The constant-current characteristic in T-LCL circuit and constant-voltage characteristic in Π-CLC are analyzed. Moreover, the total harmonic distortion of the system, the parameter sensitivity and allowable load variation are investigated. On this basis, a configure approach for the resonant circuits and a parameter design method for the system are presented. Finally, the transfer characteristics and the design method were validated by simulations and experiments.关键词
