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

这是快速傅里叶变换及逆变换的实现c代码，傅里叶变换是小波变换的基础更是图像及信号处理的基础-This is the fast Fourier transform and inverse transform of the realization of c code, Fourier transform is based on wavelet transform is the basis of image and signal processing

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
