摘要：

Light-emitting diode (LED) technology has become one of the most important luminaire, due to its environmentally-friendly behavior, high efficiency, quality of light and large lifespan. Different LED drivers based on power converters have been presented. However, most of these solutions are focused principally on low-power lighting systems, above 100 W. This paper presents a novel modular solution for 1200 W LED driver with very high efficiency. The proposed power architecture is based on a cascade connection of a DC transformer (DCX) and a partial power converter (PPC). A comprehensive comparison between different PPC configuration is presented and supported by simulations to validate the theoretical results.
