双LCL补偿ICPT系统双谐振点特性及最大输出功率研究
Study of Dual Resonance Point Characteristics and Maximum Output Power of ICPT Based on Double LCL Compensation
摘要
Abstract
The LCL inductive coupled power transfer(ICPT) system will distort inverter output currents and decrease output power when the system is at the full resonant and light load mode. Due to the problem above, this paper presented a novel work mode that the system frequency is switched to the second resonant point in the dual LCL ICPT system under the condition of a light load. The proposed control system will avoid the current waveform distortion caused by the high harmonics and maximize output power with a varying load additionally. The paper firstly analyzed the LCL compensation circuit. Based on LCL analysis, the dual LCL network was characterized by another resonant point, which will avoid the current waveform distortion. Then, a mathematical model was established to describe relationship among the output power, load and frequency, which provides a reference to maximize output power with the frequency control method. Finally, the operating characteristics of the dual resonance points were verified by simulations and experiments.关键词
