ABSTRACT
In this project, a 2KVA hybrid pure sine wave inverter with battery charging and monitoring system was designed and constructed.
The inverter circuit was designed using a power transformer rated at 2.5KVA. The DC voltage source is a battery bank rated at 24V. A high performance microcontroller (DSPic30f2010) with advanced switching and control ability was used. The inverter system doubles as an inverter and a battery charger. Pulse width modulation technique was used in the inverter design.
The inverter circuit was designed, constructed and tested. It performed satisfactorily with different house appliances such as electric fans, bulbs, refrigerator, etc.
