Design And Implementation Of A 1.5kva Single Phase Inverter

ABSTRACT

This project presents a single phase inverter system which serves as an alternative power supply. The conversion technique used is first converting the low voltage DC power to AC power using pulse width modulation (PWM), then boosted to high AC voltage using a step up transformer for constant output voltage instead of boosting the low voltage DC power to high voltage power source using a DC- DC booster which is then convetted to AC power using pulse width modulation (PWM). It is a microcontroller-based single phase inverter system which produces a sine wave output approximate to the power supplied by the national grid which is stable and reliable. This constructed project finds application in communities for residential use; social groups for powering equipment such as lightings, cooling systems and sound systems; governmental and non-governmental organizations such as academic institutions for lightings, powering equipment for Wi-Fi facility and other equipment, virtual lectures; hospitals to supply constant power to equipment needed to keep vaccines at low temperature and in Industries.
