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 ...

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 ...

In previous posts, I have introduced several do-it-yourself pwm controller circuits and reviewed several Chinese PWM controller modules. The next step in this post is to share the design of another ...

This report focuses on DC to AC power inverters, which aim to efficiently transform a DC power source to a high voltage AC source, similar to power that would be available at an electrical wall outlet ...

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 ...

Because of the widespread use of pulse-width modulation (PWM), the efficiency of a synchronous buck converter operating in this mode is well understood. However, relatively few designers understand ...

Researchers in Iraq have designed a multi-level cascaded inverter that can purportedly produce high-quality sinusoidal output voltage and current waveforms, while reduing harmonic distortion. It uses ...

Have you ever heard of PWM (pulse width modulation)? Even if you haven’t, this screen flickering issue still might impact you. But iPhone 17 looks like it will bring a long-awaited PWM fix. I had ...

The iPhone 17 models include an Accessibility setting to disable pulse width modulation (PWM), according to information found in the iOS 26 release candidate. There will be a toggle located in the ...
