Power control module with improved start requirements

Abstract

Circuits and devices are described that provide power to appliances and other devices via a power correction circuit and an LLC converter, which may for example include resonant series converters and flyback converters. The circuits and devices economize on board space, part size and power start up time by separately powering up the controller circuit portion prior to powering up the LLC converter.
