PWM relays allow engineers to go beyond simple "on-off" control to realize significant power savings and reduced heat ...

Digital pulse width modulation (DPWM) has become central to modern power conversion, enabling precise control of switching devices in DC–DC converters, inverters and motor drives. By moving the ...

A compact, high voltage pulse modulator for small scale laboratory experiments involving food, biofuel and PEF (pulsed electric field processing) is available from Diversified Technologies, Inc. of ...

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 ...

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 ...
