Design of a 100 VA Power Inverter

Abstract

An inverter is an electrical device that changes direct current (DC) to alternating current (AC). The converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching and control circuits. However, electric energy crisis is one of the major problems in the world. Electric energy stored in the form of DC. This DC must be converted into AC by using inverter when it is applied in any appliances. The inverter performs the opposite function of a rectifier. The electrical inverter is a high-power electronic oscillator. It is so named because early mechanical AC to DC converters was made to work in reverse, and thus was "inverted", to convert DC to AC. There are many devices where inverter is used, such as instant power supply (IPS), uninterrupted power supply (UPS), vehicles, etc. In this paper, we have attempted to design a 100 VA power inverter that can be used to operate an 80 watt bulb or an 80 watt fan or any equivalent kind of load.
