摘要： An electrical circuit for providing electrical power for use in powering electronic devices is described herein. The electrical circuit includes a primary power circuit and a secondary power circuit. The primary power circuit receives an alternating current (AC) input power signal from an electrical power source and generates an intermediate direct current (DC) power signal. The intermediate DC power signal is generated at a first voltage level that is less than a voltage level of the AC input power signal. The secondary power circuit receives the intermediate DC power signal from the primary power circuit and delivers an output DC power signal to an electronic device. The output DC power signal is delivered at an output voltage level that is less than the first voltage level of the intermediate DC power signal.

摘要： 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.
