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 ...

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. This method ...

The pulse width of the compact pulse cum frequency modulator can be varied by altering the change-over point of comparator IC1 with a control voltage via resistor R1. The hysteresis of the IC is ...

As engineers, you use many components and devicesevery day that you treat as black boxes. You are concernedonly about the inputs and outputs of the blackbox, and that approach is acceptable provided ...

When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

How to use unfiltered PWM to drive high power loads. How to properly set the PWM duty cycle for high power loads. How to drive an incandescent lamp using PWM. Sometimes it’s necessary to drive a ...
