A simple software method to increase the duty-cycle resolution in a digital pulse width modulation (DPWM)-controlled power ...

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 ...

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.

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 ...
