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 and a rectifier circuit for delivering input power signal to the voltage reduction circuit. The voltage reduction circuit is configured to receive an input power signal and generate an output power signal at a lower voltage level. The rectifier circuit includes a full wave bridge rectifier coupled to the electrical power source, a Zener based charging circuit coupled to the full wave bridge rectifier, a voltage divider coupled to the Zener based charging circuit and the full wave bridge rectifier, and an output terminal coupled to the full wave bridge rectifier, the Zener based charging circuit, and the voltage divider for delivering the input power signal to the voltage reduction circuit.
