摘要

提出了一种实现三相电压近正弦线电流整流的新方法。该方案包含两个升压DC-DC功率转换器，以三次谐波频率调制直流链路电流。调制后的电流被重新注入到二极管桥式整流器的交流侧。给出了三相208v(线对线)3kw系统的仿真结果。考虑了界面对系统各参数不平衡的敏感性。本文介绍了在小尺度室内模型上的实验研究结果

Third-harmonic modulated power electronics interface with 3-phase utility to provide a regulated DC output and to minimize line-current harmonics

A novel approach to achieving nearly sinusoidal line current rectification of three-phase utility voltages is presented. The scheme incorporates two step-up DC-DC power converters to modulate the DC link currents at the third harmonic frequency. The modulated currents are then reinjected on the AC side of the diode bridge rectifier. Simulation results for a three-phase, 208 V (line-to-line), 3 kW system are presented. The sensitivity of the interface to unbalances in various system parameters is included. Results from experimental investigations on a small-scale laboratory model are presented.<>
