| Abstract: | Taking environmental super - capacitors as energy - storage device, a solar illumination controller with MPPT is designed. The controller uses the ARM7 chip,LPC2103 ,as core, and MAX16834 for LED driver circuit. In order to improve the efficiency, fixed voltage and variable step-size Perturb and Observe （P＆O） method are used. The lighting time becomes much longer by software optimization. From test, The controller is found to own better efficiency and utility value than the traditional ones. |
