DESIGN OF SOLAR INVERTER USING MPPT TECHNIQUE
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 1
Abstract
This paper demonstrates the implementation of a prototype of IPS (instant power supply) system to ensure continuous output current to load in residential application utilizing both Photovoltaic (PV) energy and AC Grid. Utility interfacing PWM inverter designed here to operate by both solar energy and storage batteries that highly satisfies the necessity in rural areas where National Grids are hardly available and power cut problem reduces the effectiveness of IPS. Solar energy gets priority here to charge storage battery rather than AC source that may save hundreds of megawatts power every day. To extend the battery lifetime and keep system components hazard-free, it includes exact battery-level sensing, charging-current controlling by microcontroller unit (MCU) and a cumulative DC/AC MPPT (Maximum Power Point Tracking) charges to congregate maximum PV energy from AC Solar Modules. Investigation on improvement of power-interfacing control and optimization of overall system operation assent to intend usage recommendation in this exposition. Computer simulations and experiment results show the validity of this proposed system to have high power conversion efficiency and low harmonic distortions.
