PWM is short for Pulse Width Modulator.Because of its special performance, it is often used as dc circuit in the lamps and lanterns that move light or dc motor speed control. This circuit is made by using the principle of pulse width modulation (PWM) controller of the motor. Adopting this kind of way to control the motor speed has two advantages:
It is mainly by changing the output pulse duty ratio, the load change on the average time from 0 to 100%, in order to achieve the purpose of adjusting load brightness/speed. Using pulse width modulation (PWM) implemented dimmer/speed are the benefits of power energy can be fully used, high efficiency of the circuit. For example: when the output is 50% of the square wave, pulse width modulation (PWM) circuit of the power energy consumption is 50%, which almost all the energy is converted to load power output. And using common resistance dropping speed, the maximum output power of load for power supply 50% of its power, the power supply must provide more than 71% of the power output, the 21% of consumption on the resistance of pressure drop and heat loss.
Using pulse width modulation (PWM) mode can make full power supply voltage of the load on the job, it helps overcome motor internal coil resistance and make its produce greater torque.
