摘要
设计制作了一个太阳能充电控制器,可实现75 W太阳能电池板对蓄电池的可靠充电。主要采用Cuk电路和光耦电压反馈,并利用TL494实现PWM控制,LM393加互补功放实现驱动。通过MSP430单片机和1602液晶进行电压采样和显示。经实验论证,本方案基本完成了设计预期。
This paper presents a kind of solar energy charge controller,which may charge the batteries reliably and efficiently by 75 watt solar panels.The controller mainly uses the Cuk circuit and optical coupling voltage feedback circuit,and implements the PWM control using TL494.In the circuit the LM393 is used with a complementary power amplifier to drive.Finally,the MSP430 MCU control 1602 LCD are used to achieve voltage sampling and display.The experimental demonstration proves the design can fulfill its purpose.
