大功率UVLED分布式驱动技术研究

Research on the Technology of Distributed Driving for High Power UVLED

以工业印刷过程中UVLED固化为应用背景,研究并设计了一种UVLED驱动控制系统。分析了采用分布式驱动的优势,确定了驱动电源采用两级驱动结构,包括前端AC/DC恒压模块和后端DC/DC恒流模块。对该系统的驱动电源模块进行了试验测试和结果分析,试验结果验证了该UVLED驱动控制系统的可行性。

With the purpose that UVLED curing would be used in industrial printing, a UVLED driving and controlling system was designed. The advantage of using distributed driving was analyzed, and the driving power using two-stage drive structure was determined. The AC/DC constant voltage module and DC/DC constant current module were designed and the driving power modules were tested. The experimental results the UVLED drive control system was feasible.
