- Abstract
- A high-efficiency multicharger system for photovoltaic energy harvesting is presented in this letter. The multicharger system is widely used for module-integrated converts to offer a good antipartial shading property. The proposed efficiency-aware cooperative control enhances the total power conversion efficiency of the system ((TOT)) by making chargers help each other when there is a difference between the input powers to each charger due to the partial shading. The system is implemented using a 0.5-m CMOS technology. The (TOT) and the power range (for (TOT) > 80) are improved by 14 (power difference 1.082 W) and 0.61 W (lower photovoltaic cell power 43mW), respectively.
