摘　　要：为解决多电飞机变频供电体制下的负载恒频供电问题,研制了一款SVPWM整流器。首先对三相半桥电压型整流器(以下简称VSR)进行数学建模,然后给出一种SVPWM的简化算法。以TMS320F2812为控制核心搭建整流器的原理样机,分别在不同频率的网侧交流输入下实验,结果显示整流器输出能够很好地跟踪给定值并且保持稳定,网侧输入电流实现正弦化并且与输入电压保持同相位,实现了高功率因数整流。In order to supply loads of the constant frequency in the variable frequency power supply system, a SVPWM rectifier is developed. First, mathematical modeling of VSR is made. Then a simplified SVPWM algorithm is presented. The model machine of the rectifier is made to test the performance of the rectifier based on the variable frequency power supply. Experiment results show that the output of rectifier is stable and can precisely track a given value according to the results. The rectifier achieves high power factor operation.
