Platform strategy by uniting solar, thermal, vibrational and wind energy with maximum power point tracking system

This paper presents the power generation through multiple sources where maximum power point tracking system is used to achieve maximum efficiency. A platform strategy by uniting different kinds of energies was presented by researchers. The dynamic and static performance is theoretically analyzed and design criteria are provided. Due to variations in Dc voltage, the change in wind speed is detected. DC current is then used as a disturbing variable for WECS in MPPT algorithms. By using this technique, 15 to 20% efficiency of the system is improved. The system consists of specific several inputs and outputs switching matrixes that associate the energy from four discrete systems of energy harvesting sources such as: thermoelectric, wind electric, piezo electric and photovoltaic. The system can hold input voltages from 50 mV to 6 V and is proficient of removing maximum power and efficiency from all individual sources and combines them by using a single inductor and capacitor. A projected time base power monitoring system is used in obtaining MPPT for the photovoltaic harvester. The control circuits and the switch matrix are executed on a 0.36 m CMOS (Complementary metal oxide silicon) process. The peak efficiency of 97% was recorded using maximum power point tracking algorithm.
