Single phase offline LED lighting system based on Twin-Bus configuration
Pages: 7-12
Year: Issue:  3
Journal: Electric Machines and Control

Keyword:  Twin-Bus Buck变换器调光离线式LED照明单相;
Abstract: 针对单相离线式发光二极管驱动电源效率低的问题,跟据发光二极管照明电源的特点,提出一种Twin-Bus型的发光二极管照明驱动架构.基于发光二极管照明驱动架构,研究了适合于该架构的可PWM调光的降压型变换器.详细讨论和分析了变换器的工作原理、控制策略、PWM调光策略.以高效率的LLC谐振变换器为例,讨论了Twin-Bus电源的实现理念,Twin-Bus电源的实现理念可以推广到任何隔离性AC-DC变换器...
