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 ...

Texas Instruments Incorporated introduced an off-line green mode pulse width modulation (PWM) controller that minimizes space and system cost while providing high efficiency in power supply ...

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 ...

Apple had a lot to say about its new phones during the “Awe Dropping” event Tuesday, but there were plenty of little features that couldn’t fit in the keynote. One interesting feature spotted in 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 ...

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 ...

Apple successfully released the new iPhone 17 lineup and iPhone Air with promising features to improve the user experience, but something went under the radar during the announcement. One new feature ...

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 ...

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 ...
