大功率LED驱动电源研究

Research on High Power LED Driver Power Supply

随着节能环保的不断发展,高能效照明逐渐成为了研究热点。针对大功率区域照明电源设计了适合线性灯、线槽灯的分布式方案,增强了系统的灵活性;同时设计了适合洗墙灯、外墙灯的整体式/单段式方案,减少了元器件数量,降低了系统成本;最后设计了新型LED照明拓扑结构,实现了极高能效,且具备了多种故障保护特性。本文相关成果有利于大功率LED驱动电源的优化设计。

With the continuous development of energy-saving and environmental protection,energy-efficient lighting has gradually become a research hotspot.A distributed scheme suitable for linear lamp and slot lamp is designed for high-power area lighting power supply,which enhances the flexibility of the lighting system.At the same time,a monolithic/single-section scheme suitable for LED wall washer and wall lamp is designed,which reduces the number of components and system cost.Finally,a novel topology of the LED lighting system is designed,which has the characteristics of very high energy efficiency and a variety of fault protection.The results of this paper are beneficial to the optimal design of high-power LED driving power supply.
