基于谐振电容阵列的CPT系统输出控制方法
Study on Output Voltage Stability of CPT System Based on Resonant Capacitor Array
摘要
Abstract
Aimed at output voltage control of contactless power transfer (CPT) system, a novel capacitor array regulating strategy is presented. A special resonant capacitor array structure is designed for the strategy at the secondary side of the CPT system. The computing method of the array equivalent capacitance is also given. Furthermore, the relation between the array capacitance and the output voltage is analyzed and the output voltage regulating method is presented based on the switching among the array capacitors. The output control is realized by a piecewise control algorithm according to the output error amplitude. The control strategy can directly realize output control and satisfy the requirements for multi pickup and wide range control instead of using any auxiliary regulating stage. Finally, experiment results verify the capacitor array structure and the output control strategy.关键词
