：SPWM调制技术是通过改变输出方波的占空比来改变等效的输出电压，其调制波为正弦波，脉冲宽度间占空 比按正弦规率排列， 这样输出波形经过适当的滤波可以做到正弦波输出。它广泛的用于支流交流逆变器。本次实 验使用Matlab/Simulink对SPWM技术进行仿真并分析数据。(: SPWM modulation by changing the duty cycle square wave output to change the equivalent output voltage, the modulated sine wave, pulse width, duty cycle between the rate at sine arranged so that the filter output waveform can be done properly to the sine wave output. It is widely used in branch AC inverter. The experiment uses Matlab/Simulink simulation of the SPWM technique and analyze data.)
