摘要
为了提高整流器的功率因数,获得能够快速响应和直流电压稳定输出的直流电源,设计一种基于SVPWM和DSP的三相电压型整流器。通过对三相VSR及五段法SVPWM的工作原理进行分析,完成了整流器的硬件电路设计和相关的软件设计,并研制了实验样机。实验结果表明:采用SVPWM控制的整流器能够有效地降低谐波,提高功率因数。
In order to increase the high power factor,and acquire the fast dynamic response and the DC power with the steady output voltage,the three-phase voltage rectifier based on SVPWM and DSP is designed.The operation principles of the three-phase VSR and the five-segment SVPWM control strategy are analyzed,and the design of the hardware circuit and the corresponding software of the rectifier are finished.The experiment results show that the rectifier based on SVPWM can availably decrease the harmonic pollution and improve power factor.
