Abstract:
ABSTRACT Nowadays technology is growing very fast and our conventional sources of energy are limited and hence they are depleting. If these sources are used continuously, there will be no conventional sources in future. Solar and wind technology are most promising technology with battery storage system. With this we need a very robust interfacing device that can connect the battery storage system with the grid. These energy systems are not reliable to feed the power as a standalone system because of the large fluctuations in output and hence these energy system are always connected with energy storage devices such as batteries and super capacitors. These energy storage devices store the surplus energy during low demand and provide backup in case of system failure. A conventional dc-dc converter can be converted into a bidirectional converter using bidirectional switch by using diode in anti-parallel with MOSFET or IGBT allowing current flow in both the direction using controlled switching operation. Charging and discharging is based on the state of charge of the battery and direction of the current. Algorithm for charging and discharging of battery is proposed and given in upcoming sections. The constancy of the both charging voltage, discharging voltage, charging current, discharging current and the automatic switching of the system is tested via simulation. Hence there is no chance of overcharging of battery that leads to reduction in the life of battery. Keywords: Bidirectional, half-bridge, efficiency, switching, PMDC motor, Converter.
