摘要
本文针对太阳能LED照明系统,研究了一种将Boost全桥变换器与LCL恒流谐振网络相结合的光伏LED路灯系统及其控制策略,详细分析了该变换器电路组成及工作原理,并提出通过PWM控制实现太阳能电池的最大功率跟踪及对蓄电池的三阶段式充电,通过移相控制,实现对输出电流的恒定控制。最后,研制了一台基于LCL恒流谐振网络的光伏LED路灯驱动电源实验样机,样机实验结果验证了所提出方案是可行的。
This article focuses on solar LED lighting systems,researched an boost full-bridge converter combine with LCL constant-current resonant network photovoltaic LED street lamps and its control strategy.Detailed analysis of the circuit composition and working principle of the converter,and proposed to realize the maximum power tracking of solar cells and the three-phase charging of the battery through PWM control.Through phase shift control,achieve constant control of the output current.At last,developed an experimental prototype of photovoltaic LED street lamp driving power supply based on LCL constant current resonant network,and prototype experiment results verify that the proposed scheme is feasible.
