摘要
发光二极管(LED)技术以其环保、高效、光质和寿命长等优点，已成为最重要的照明技术之一。已经提出了基于电源转换器的不同LED驱动器。然而，大多数这些解决方案主要集中在100w以上的低功率照明系统上。本文提出了一种新颖的模块化方案，用于1200 W LED驱动器，具有很高的效率。提出的电源架构是基于直流变压器(DCX)和部分功率转换器(PPC)的级联连接。对不同的PPC结构进行了全面的比较，并通过仿真验证了理论结果。
Partial Power Converter for DCX-based High-Power LED Drivers
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.
