基于FPGA的AC-AC谐振变换器实现

摘要

研究了一种适用于非接触电能传输系统、实现低频到高频直接变换的AC-AC谐振变换器的恒幅控制策略,分析了该变换器的运行模式,设计了基于FPGA的控制系统,并通过实验验证了系统方案的有效性.%This paper studies a constant-magnitude control strategy of an AC-AC resonant converter and its implementation.The studied converter, which is designed for contactless power transfer systems, can directly convert a low frequency input AC source to a high frequency AC output with quasi constant magnitude. The operating mode of the converter are analyzed. Then a control system based on FPGA is designed and verified experimentally.
