Abstract

The paper presents a novel approach to efficiency optimization applied to modular DC/DC converters. It consists of using several identical converters in parallel, turning on just as many of them as needed and operating them with maximum efficiency, while leaving only one of them working in a suboptimal operating point. The conditions for switching on or off a converter are also investigated to obtain maximum overall efficiency. Notable improvement can be obtained in the entire load region, especially at light load.
