摘要
提出了一种基于高频交流链接技术的串联谐振变换器,简要分析了该变换器的工作原理及一个周期内的工作过程,给出了变换器的控制方式和控制系统的框图,并进行了仿真和实验验证。实验结果表明,该变换器能够实现网侧电压和电流同相位,且网侧电流谐波含量低,同时串联谐振又具有高效率和恒流特性。因而,变换器具有高功率因数、高效率和低谐波的优点。
Abstract
This paper proposes a series resonant converter based on HF (high-frequency) AC-link technology, and gives the analysis of its working principle and working process, as well as the control method and system block diagram. Simulation and experiment ware carried out, and the experimental results show that the converter can make the grid-side voltage and current in the same phase, and the grid-side current harmonic level is low. Besides, series resonance has high efficiency and constant-current charging characteristics. Thus, the converter has high power factor, high efficiency and low harmonic.
