In pulse position modulation, the amplitude and width of the pulses are kept constant, while the position of each pulse with reference to position of reference pulse, is changed according to the ...

Pulse Width Modulation (PWM) is a fundamental technique in power electronics that facilitates the efficient control of power delivery by modulating the width of voltage or current pulses.

Here is a simple attempt to fill a niche that seems to be lacking in the power inverters world — one for which a fairly efficient, inexpensive “inverter heart” offers a pure sine wave output.

A simple and effective solution is to use the pulse-width-modulation (PWM) output from a microprocessor to drive the load through a switched MOSFET.
