Abstract
The intent of this proposed work is to maintain a suitable DC voltage for high power Light Emitting Diodes (LED) from a variable low DC voltage obtained from the solar PV array. Normally, a high gain switched-capacitor DC-DC converter is employed to boost output voltage. Ironically, due to the varying nature of solar PV, the output obtained from the converter also changes. The Proportional Integral (PI) controller that is used to regulate output voltage takes a considerable amount of time to attain its steady-state voltage. To overcome this, fuzzy tuned PI controllers are proposed. The performance comparison of these controllers is analyzed with respect to the settling time of converter DC output voltage. The simulation of the converter with a proposed controller is done for a power rating of 200 W, and the output settling time with the fuzzy PI controller is less compared with that of the PI controller.
