摘要
为了使三相逆变电源输出电压波形更接近于正弦波,针对SVPWM调制技术的特性介绍了一种三相LC低通滤波器的设计方法。该设计方法综合了频率特性、功率因素以及无功容量最小等因素来优化滤波器L、C参数设计,使滤波器输出电压中谐波量大大减少。最后,在Matlab/Simulink仿真中验证了该方法的正确性。
In order to make the output of the three-phase interver closer to the sinusoidal waveform,this paper introduces a design method of three-phase LC low-pass filter according to the SVPWM characteristics.This approach considers multi-element such as frequency characteristics,power factor and minimum reactive capacity to optimum filter parameters L,C,so that harmonic of filter output is greatly reduce.Finally,Matlab / Simulink simulation verify the correctness of the method.
