Electrical circuit for delivering power to consumer electronic devices

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.

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 forward converter coupled to the input and output terminals. The forward converter includes a transformer, and a primary side regulation circuit coupled to a primary side of the transformer. The primary side regulation circuit includes a switching device coupled to the primary side, a current sense circuit configured to sense a current level on the primary side, and a controller configured to generate a pulse-width modulated control signal delivered to the switching device as a function of the sensed current level to regulate the transformer to deliver the output power signal at a desired voltage level.
