How to Wire PWM Speed Regulation?

02/21/2024

PWM (Pulse Width Modulation) is a technology that equivalently obtains the required signal by modulating the width of a series of pulses. From the waveform point of view, it is a square wave with constantly changing high and low levels. signal, there are three factors that affect the output of the PWM signal, namely frequency, amplitude and duty cycle. The frequency affects the period of the PWM signal, the amplitude determines the high-level voltage, and the duty cycle directly affects the effective value of the PWM signal.
