Abstract
A power supply (100) includes an energy source (102) which provides cyclically varying supply voltage having periodic repeated beginning points. Generally, the beginning points comprise zero potential points of the cyclically varying supply voltage. The energy source is coupled to an energy control means (106) which is responsive to a control setting for controlling an output (108). A controller (114) provides the control setting in response to a feedback signal received from a sensor (116) only at the beginning points and maintains control of the control setting constant until a subsequent beginning point.
