【正文】 article does not talk . battery charging circuit The traditional way of charging the battery fast charge, overcharge and float three the battery can receive the maximum current is generally large, practical applications of solar cells unable to provide maximum battery can receive current, and thus the traditional threestage charging mode can not be effectively applied to solar charging of the battery . This design uses MPPT charging, constant voltage charging and floating charge scheme instead of the traditional three stage charging mode, allowing the system to improve the utilization of solar energy , while extending the battery life. The specific design of the charging circuit shown in . In this paper, the MOSFET diodesreplaced, namely synchronous Buck. MOSFET, with very low onresistance can be achieved usinga diode is much higher than the conversion efficiency of solar energy to minimize the losses, andwill not cause serious thermal problems. For the MOSFET operates in the best condition, its drivercircuit using IR 39。實(shí)驗(yàn)結(jié)果表明,該控制器的性能可靠,可以監(jiān)控實(shí)施太陽(yáng)能電池和蓄電池,電池充狀態(tài)放電控制最佳的,以延長(zhǎng)電池的使用壽命??刂破?. 簡(jiǎn)介。太陽(yáng)能。s input voltage range of ~ 40V, LED column by side detection output current,output voltage is + ~ 60V, efficiency boost mode over 94% , using the PWM dimming signal ,dimming ratio of up to 3000:1 , using the CTRL pin can be simulated 10:1 dimming, with open LED protection, programmable under voltage lockout hysteresis and programmable softstartFunction. LED constant current drive circuit schematics LED drive current size by the CTRL pin voltage LT3755 and R20 resistance to work together to determine when the pin voltage is below , the voltage by adjusting the current flowing through them can be achieved on the conduct of 10:1 LED adjusted to achieve the purpose analog dimming .According to this feature of the LT3755, the PWM output pin microcontroller CCP0_3 processing and filtering the CTRL pin LT3755 is connected in parallel with the number depending on how many LED, PWM duty cycle through preset, to set the LED drive current purposes. Through the MCU pin output PWM duty cycle adjustment, you can control the LED light intensity and power output, to digital dimming purposes. R20 while LED highside current sense resistor for LED short circuit protection, short circuit when the LED, LT3755 off its PWM output, constant current source circuit to stop working.4 System Software DesignSystem software flow chart below:5 Summary Solar LED street lighting system is the perfect bination of solar energy development andutilization of a new generation of green light LED.
