All type of electronic devices requires power supply from electric power sources for their operation. Emergency power system can rely on generators or uninterruptible power supplies. 1ģ They find uses in a wide variety of setting from residential homes to hospitals, scientific laboratories and computerized systems. Emergency power systems are types of systems, which may include lighting generator and other apparatus, to provide back up resources in a crisis or when regular systems fail. Emergency back-up power system can provide electrical power to critical loads or the whole house during power outages. The inverter system is capable of providing power to the appropriate load for up to eight hours depending on the state of the 12V batteries KEYWORDS: Inverter, electricity generation, Multisim, square wave, Proteus Received for Publication: 07/06/16 Accepted for Publication: 11/09/16 Corresponding Author: INTRODUCTION Due to today s total dependence on electricity and because of frequent electrical power outage, back up power is becoming a necessity. The oscilloscope measurement tallied with the set frequency of 50Hz and the square wave oscillator output. The assembled composite unit worked well. The inverter circuit in this project work is based on the operation of the IC CD V AC is stepped up to 230V AC by using a step up transformer.
The values of the various components were determined before the simulations were embarked upon using electronic workbench: Multisim and proteus software respectively. In this project work, a 500W power inverter system was designed, simulated and constructed. An inverter is essentially the opposite of a rectifier. The converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching and control circuits. ABSTRACT An inverter is an electrical device that converts direct current (DC) to alternating current (AC). Departmet of Electrical/Electronic Engineering, Maritime Academy of Nigeria, Oron, Nigeria.
