Abstract

This project gives a deep insight of an inverter system. This includes the theories and literatures that govern the implementation of an inverter, components of an inverter system, methodology adopted to physically achieve the inverter system. The 3.5KVA inverter is designed to have an input voltage specification of 24V, output voltage of 220V and a frequency of 50Hz, these specifications were designed such that it synchronizes with the standard parameters of Nigerian electrical distribution companies, such as the Enugu Electrical Distribution Company (EEDC). The core purpose of this design is to combat epileptic nature of power supply in Nigeria by serving as a backup supply when the primary source of power fails and also charge the batteries when the utility is active. A pulse width modulation technique using a H-bridge circuit was utilized to achieve a frequency of 50Hz and with aid of MOSFETs, a sinusoidal signal equivalent to the battery voltage is gotten at the output of the H-bridge, this is sent to a transformer which transforms the 24V AC to 220V AC.
