The pulse-width modulation (PWM) controlling DC Power If you have to control small motor speed or light levels, the general perception is to adjust the supply voltage and current to change the power, but efficiency of this method is poor, if using the following PWM to adjust the DC output can improve the above problems. It is based on the length of the output power and the interval of time to change the output power.
