[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered … ...

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters ...

The approach combines virtual impedance and a modified pulse-width modulation strategy to suppress fault currents in grid-connected PV systems.

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.
