摘要 简要介绍了SPWM逆变器的组成以及工作原理。分析了逆变器在风机转子侧的作用,在Matlab/Simulink中进行了建模仿真,通过实例研究逆变电路的输入输出及其特性。根据仿真结果对影响逆变效果、电压畸变率的因素进行分析,得出可以通过调整滤波器电容、载波频率来保证畸变率在规定范围。 A brief introduction of composition and operation principle of SPWM inverter. Analysis of the inverter effects on the fan rotor side. Modeling and simulation in Matlab / Simulink. Through the case studies of the characteristics and input/output of the inverter circuit, the effects of influencing factor on the inverter and voltage distortion rate is analyzed. It' s concluded that by adjus-ting the filter capacitor and the carrier frequency to ensure that the distortion rate maintained in the predetermined range.
