Abstract
An electrical circuit for providing electrical power for use in powering electronic devices, such as monitors, televisions, white goods, data centers, and telecom circuit boards, is described herein. The electrical circuit includes a voltage reduction circuit cell that includes a first capacitor, a second capacitor, a switching circuit, and a hold capacitor. The switching circuit includes a plurality of switching devices that are coupled to the first and the second capacitors for delivering power from an input terminal to an output terminal. The plurality of switching devices includes at least two switching devices that are coupled to ground. The voltage reduction circuit cell also includes a controller for operating the switching circuit in a plurality of operational modes to deliver an output power signal at a desired voltage level.
