Development of PV inverter/charger system

Nowadays, fossil fuel is the main energy supplier, but the recognition of it as being a major cause of environmental problems makes the mankind to look for alternative resources in power generation. The renewable energy such as solar energy could replace fossil based energy generation such as fuel and coal. This study relates with development of a converter system. This works use solar as the renewable supply energy. This works involves the development of converter system to recharge the battery as a backup supply for this system. This system use charging circuit for charges the rechargeable battery and single phase half-bridge inverter use for convert the DC power to single phase AC power. The charging circuit utilizes the three modes of the battery charging process; normal or bulk charge, finishing or float charge and equalizing charge. To convert DC to AC power, single phase half bridge inverter square wave is used in this project.
