A regulator is an electronic device that supplies power to other devices. Devices powered by regulators are called consumers. They consume power provided by regulators. Most regulators can enable and disable their outputs, and some can also control their output voltage or current. The driver should expose those capabilities to consumers by means of specific […]

Pulse Wide Modulation (PWM) operates like a switch that constantly cycles on and off. In the control and command world, it is a hardware feature that’s used to control servomotors, for voltage regulation purposes, and so on. The most well-known applications of PWM are motor speed control, light dimming, voltage regulation, and, in some cases, […]
