Pulse width modulation Pulse width modulation (PWM), or pulse duration modulation (PDM), is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts. The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast rate. Yet Another Simple Pot controlled 555 PWM Generator: 4 Steps About 60% of the energy gets burned off as heat in the resistor in the first circuit, while in the second circuit, almost all of the energy supplied is used. This is why PWM is useful. It allows a signal to range from completely off to completely on. Electronic boost controller, PWM signal generator The valve is 12v, 5.4 watts 25.4 ohm coil and runs at .45 Amps at 12v run on PWM. I assume the signal generator doesn't put out the power that the valve wants, but I can't seem to find how to step that signal up to what it wants. I have tried multiple transistors but can't figure out if I am wiring it in correctly.
