研究一种基于高频交流链接技术的新型并联谐振变换器，给出该变换器的电路拓扑图，并对其工作原理进行理论分析。然后使用Matlab中的Simulink仿真模块对该并联谐振变换器进行了仿真研究，仿真结果表明采用高频交流链接技术的新型并联谐振变换器输入端三相电流与输入端三相电压基本同相，具有高的功率因数和低的谐波含量。该变换器不仅体积小，结构紧凑，电源的功率密度高，同时由于谐波分量较低给电网带来的环境影响小，使整个电网系统供电效率更高。

A new parallel resonant converter based on high frequency AC?link technology is studied,in which the circuit to?pology is provided,and its working principle is analyzed in theory. The parallel resonant converter is simulated with Simulink simulation model in Matlab. The simulation results show that the phases of the three?phase current and three?phase voltage in in?put end of the new parallel resonant converter are basically the same,the power factor of the converter is high,and the harmonic content is low. This converter has small size,compact structure,and high power density of the power supply. Because of the low harmonic component,it has brought little environmental influence to power grid,and makes the whole power grid system have high efficiency.
