PWM control is a technology that modulates the width of a pulse, that is, by modulating the width of a series of pulses, the required waveform (including shape and amplitude) is equivalently obtained. Modulation: Adding the relevant information of a waveform (modulation reference wave) signal to another waveform (carrier). PWM control technology is most widely used in inverter circuits, and has the most profound impact on inverter circuits. Among the inverter circuits that are widely used now, the vast majority are PWM inverter circuits. It can be said that PWM control technology has developed to a relatively mature level and determined its important position in power electronics technology precisely because of its application in inverter circuits.
