Abstract
A circuit for converting an AC potential to a regulated DC potential which circuit consumes a minimum of power and is relatively inexpensive to build is described. A capacitor is used to couple the AC potential to a rectifier. The duration of current flow through the capacitor is controlled to obtain the regulation. An on or off switching device is used such as an SCR, eliminating the current flow regulation devices often used in regulative power supplies. The invented circuit is particularly useful for providing a regulated DC potential in a switching power supply.
