Description
Recent regulations promote high power supply efficiency over wide load ranges, and they impose limits for the maximum AC power during idle and no-load conditions. This work describes a power system architecture proposed to meet these new efficiency goals. The features of this architecture include operation in multiple modes where each mode enhances the efficiency within its power range. A fly back converter is high-lighted as a solution for low to medium power applications, a topology that can be controlled in burst, frequency fold back, discontinuous conduction, and quasi-resonant modes, that are shown to enhance efficiency from no-load to full-load, respectively. In addition to the design steps, this topic also includes test techniques and performance verification.
