The singlechip realizes the switching of the switch device in the inverter circuit, which is controlled by the pulse width according to the sine law and the PWM waveform equivalent to the sinusoidal wave, that is, the SPWM waveform. The area of the output pulse voltage is equal to the desired output sine wave in the corresponding interval, and the frequency and amplitude of the variable modulation wave can be adjusted to the inverse. The frequency and amplitude of the output voltage of the circuit are changed to control the output voltage of the inverter.
