Petrochina daqing petrochemical company refinery, heilongjiang daqing 163711) Abstract: the control scheme LED by solar inverter, battery charging and illumination component driving subsystem of solar LED street lamp integrated control system is realized And circuit design and analysis of related technologies. Inverter subsystem adopts DC/DC booster and DC/AC inverter piecewise control, DC/DC mining with maximum power tracking (M PPT) output stable DC, DC/AC section USES the voltage loop current inner loop control and reactive power detection feedback and electric current feedforward control of integrated control technology. The battery charging subsystem USES segmented charging strategy and control technology to ensure that the battery pack is fully charged and the battery is overcharged to ensure that the accumulator can work in a long period of time. Finally, by comparing various white LED driving schemes, the optimal driving scheme of white leds is determined to control the brightness of the const
