PWM Signal Generators
V3.02 27-Jul-04 Testing
status: Mixed. Some untested, some SPICE simulated.
1. Introduction
PWM, or Pulse Width Modulation, is a method of controlling
the amount of power to a load without having to dissipate
any power in the load driver.
Imagine a 10W light bulb load supplied
from a battery. In this case the battery supplies 10W of power,
and the light bulb converts this 10W into light and heat.
No power is lost anywhere else in the circuit. If we wanted
to dim the light bulb, so it only absorbed 5W of power, we
could place a resistor in series which absorbed 5W, then the
light bulb could absorb the other 5W. This would work, but
the power dissipated in the resistor not only makes it get
very hot, but is wasted. The battery is still supplying 10W.
An alternative way is to switch
the light bulb on and off very quickly so that it is only
on for half of the time. Then the average power taken by the
light bulb is still only 5W, and the average power supplied
by the battery is only supplying 5W also. If we wanted the
bulb to take 6W, we could leave the switch on for a little
longer than the time it was off, then a little more average
power will be delivered to the bulb.
This on-off switching is called
PWM. The amount of power delivered to the load is proportional
to the percentage of time that the load is switched on.
In the chapter on speed
controllers on this site, there is an explanation why PWM
signals are used to drive speed controllers. It is the same
