摘要
针对传统三相电压型PWM整流器谐波含量大的特点,设计了一种基于DSP2812和空间矢量控制(SVPWM)的新型整流器。通过仿真实验发现,该整流器能够使网侧电压与电流同相位,实现了高功率因数整流,并且具有较强的稳定性和抗干扰能力。
The traditional transform rectifier with high total harmonic distortion( THD) widely affects the quality of the power system. One new rectifier based on DSP2812 and Space Vector Pulse Width Modulation( SVPWM) is designed in this paper. The simulation experiment results show that the phase of input current is identical to its input voltage and the rectifier realizes high power factor by adopting the SVPWM current control method. It has the strong stability and anti-interference ability.
