An efficient method of MPPT tracking system of a solar powered Uninterruptible Power Supply application

The study deals with an innovative system achieving an alternative source of energy supply from photovoltaic energy system which operates in case of utility power failure and provides continuity of supply even in medical appliances or industrial applications. It is also designed to reduce usage of utility supply which is generated from coals, nuclear having more carbons as outlets, lagging of sources and providing impure power to consumers. But the solar power is a pure and precious resource and no more impure outlets other disadvantages as like high initial cost. But the economical status may be improved in future but we may not have resource to generate power sometimes. So cost criteria can be meeting out in future to generate power from solar energy. The proposed PV system is composed of conventional novel single axis tracking system and PV system with DC-DC boost converter and PWM voltage source inverter. Here the tracking system is designed to get always 12 V dc output. This voltage is taken as input to the proposed method to maximize the output.
