power consumption

PWM finds diverse use in automobiles especially in actuators, motor voltage and current control. PWM technique reduces power consumption & increases efficiency.

Pulse width modulation also known as pulse time or pulse duration modulation reduces the average power delivered to a load by chopping electrical signals into discrete parts.

The average voltage and current delivered to the load is controlled by ON and OFF switching at a particular frequency, mostly at a fast rate.

The longer the switch is in the ON position relative to OFF position, the higher the total power supplied to the load.
