In industrial and process control, it is often necessary to accurately control the temperature of a process. You control most heating elements using the “bang-bang” method—turning the power to them on ...

The new power controller AC-THOR 9s can control both electrical room heating and water heaters up to 9 kilowatts of power linearly. It controls three-phase heating elements or up to three electrical ...

This design describes a simple, cost-effective solution for an ac power controller using PC-compatible conduction-angle control. A solid-state relay (SSR) is activated through a pulse-width-modulated ...

The iW1700 zero-power ac/dc digital PWM controller enables low-cost, energy-efficient 120/230V-ac offline adapters and chargers requiring as much as 5W, which consume zero no-load power for cell ...

The harnessing of electricity has played a pivotal role in human history and has exponentially expedited our growth as a species. Since becoming a household commodity in the late 19th century, ...

Rectifiers and ac-dc power supplies employ large bulk capacitors. During power-up, these capacitors require a large amount of current to charge up, resulting in a large inrush current. This inrush ...
