Introduction to PWM:
The full name of pulse width modulation: Pulse Width Modulator, referred to as PWM. Because of its special properties, it is often used as a dimming lamp in the DC circuit or a DC motor speed. This circuit is a motor controller made using the principle of pulse width modulation (PWM).
There are two advantages to using this method to control the motor speed:
It mainly changes the duty ratio of the output square wave, so that the average on-time on the load changes from 0-100% to achieve the purpose of adjusting the brightness/speed of the load. The advantage of using pulse width modulation (PWM) to achieve dimming/speed regulation is that the energy of the power supply can be fully utilized and the efficiency of the circuit is high. For example, when the output is a 50% square wave, the power consumption of the pulse width modulation (PWM) circuit is also 50%, that is, almost all the energy is converted into load power output. While using the common resistor step-down speed regulation, for the load to obtain 50% of the power output power of the power supply, the power supply must provide more than 71% of the output power, of which 21% is consumed in the voltage drop and heat consumption of the resistor.
