Pulse Width Modulation (PWM) Put simply PWM is the process of switching power ON and OFF to a device in pulses at a specific frequency. Same approach used in commercial light dimmers, DC motor speed controller, CPU fan speed controllers and etc. Testing a Pulse Width Modulated Circuit One method to accomplish this is called the pulse width modulated (PWM) circuit. It is found in many places on modern engines and equipment. An electronic fuel injector (gas or diesel) is the most common use of a PWM circuit, but it is not the only one. In most diesel applications, the exhaust gas recirculation valve is PWM controlled also. PWM Pulse Width Modulation for DC Motor Speed and LED ... A pulse width modulation signal begins with a voltage that goes up and down repeatedly. The classic method of creating the oscillation is with a resistor capacitor (RC) circuit. This circuit uses RC timing with a diode twist to alter the ratio of the on pulse time versus the off pulse time (called “duty cycle”). Pulse Width Modulation DC Motor Control This circuit is not a true pulse width modulation control. Because only the frequency of pulses varies, it is really pulse frequency modulation. This works, though not as well as true PWM.
