摘要
研究了一种高频无极灯独立光伏照明系统,利用一个多输入DC/DC变换器实现了太阳电池对蓄电池充电以及蓄电池对无极灯镇流器供电。与传统的独立光伏照明系统相比,新系统结构简单,延长了蓄电池的使用寿命,仅用一个MCU就实现了对变换器的数字控制和系统能量管理。正文中对系统进行了详细分析与设计并对其进行了实验验证。
A novel stand-alone photovoltaic lighting system with electrode-less discharge lamp was proposed in the paper. Compared with the traditional stand-alone photovohaic lighting system, one multi-input DC/DC converter was used to con- trol the battery charge or discharge effectively, protect battery and prolong its natural life. Energy management and digital control of converter are implemented by one MCU. The system was analyzed in detail, and the experimental verifications were also presented.
