该模型模拟了单相方波逆变器，使用MATLAB环境。-Single Phase square wave inverter

基于Matlab simulink搭建的方波逆变器仿真模型，模型正确可直接使用-Square wave inverter simulation model based on Matlab simulink structures, the model is correct and can be used directly

用脉冲宽度按正弦规律变化而和正弦波等效的PWM波形即SPWM波形控制逆变电路中开关器件的通断，使其输出的脉冲电压的面积与所希望输出的正弦波在相应区间内的面积相等，通过改变调制波的频率和幅值则可调节逆变电路输出电压的频率和幅值-With pulse width according to the sine law of change and equivalent sine wave inverter PWM waveform of SPWM waveform control circuit swit
