Abstract
A device which rectifies and regulates high voltage alternating current without the use of transformers, large capacitive coupling circuits or high voltage linear regulators. The device includes a rectifier, a control circuit for sensing the output voltage of the rectifier and switching on and off the input power, a storage capacitor and a low voltage linear regulator. The control circuit, which incorporates a voltage sensing circuit and a switch, limits the output voltage of the rectifier as seen by the linear regulator.
