直流母线供电的LED教室照明系统设计

Design of LED Classroom Lighting System Based on DC Bus Power Supply

针对以太阳能光伏发电为供电电源的楼宇照明系统应用需求,研究设计了一套新型的基于直流母线供电的LED教室照明系统,详细介绍了系统的组成,并对其专用驱动电路及控制器系统进行了设计开发。该系统较常规交流供电系统可大幅减少电能变换损耗,提高系统的供电效率和电能利用率,特别适用于利用太阳能等新能源供电的楼宇照明系统。最后通过测试实验,验证了该系统适用性和优越性。

For the application requires of building lighting systems with solar photovoltaic power supply,a novel LED classroom lighting system based on DC bus power supply was designed,and the system structure principle and composition are described in detail,the special driver circuit and control were designed and implemented.Comparing with the conventional AC bus power supply system,the proposed system can significantly reduce the power conversion loss and improve the efficiency of system and power utilization,which particularly applies to the lighting system powered by solar and wind energy,etc.Finally,the test experiments verified the superiority and applicability of the designed system.
