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 an input terminal configured to receive an input power signal, an output terminal configured to provide an output power signal, and a plurality of voltage reduction circuit cells coupled between the input terminal and the output terminal. Each of the voltage reduction circuit cells includes a pair of flyback capacitors, a switching circuit, and a hold capacitor. The switching device is configured to operate the corresponding voltage reduction circuit cell at a charging phase and at a discharging phase. The plurality of voltage reduction circuit cells are configured to deliver the output power signal having a voltage level that is less than the voltage level of the input power signal.
