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 ...

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 ...

I picked up some pulse width modulation to voltage converter modules. You’ve seen these before under a variety of names. They look amazing for the price, but there are a few little things you might ...

Embarking as third-generation Fusion digital power controllers, the UCD9240 4-output, multi-phase power system controllers integrate digital pulse width modulators with a 250-ps resolution.

In the realm of test equipment, there are a number of items that you don’t know you need until you need one. That’s probably the case with the HP11720A pulse modulator. [Tom] acquired two of these ...
