Construction of UPS (Uninterruptible Power Supply) using 12v DC for 240v AC output Department:Electrical Electronics Engineering By: uzogood4u Project ID: 5347 Rating: (5.0) votes: 1 Price:₦3000 Get the Complete MaterialAbstractAn uninterruptible power supply has been designed, constructed and tested. It has a battery driven inverter that gives an output of 1000VA, thereby inverting a 12V D. C. source to 240V ac output. The power unit was able to convert the 240V ac line supplies from NEPA to DC supply and also change the batter by converting the AC supply to DC output required for battery charging. The IC type multivibrator or oscillator amplify the DC from the battery and gives an output of 50Hertz required by the electrical appliance. Finally, the UPS was able to generate a rating of 1000VA, 240V ac from the battery supply when there was a power failure and it gives square wave of 50Hz frequency. This project is divided into six chapters. Firstly, the introduction, history and development of the UPS with aims and objectives. Secondly, literature reviews, meaning of UPS, types of UPS and the functions of UPS, and components of the UPS. Thirdly, the transformer, fourthly, the battery charger/rectification, block diagram, schematic diagrams and principle of operation of the UPS. Finally, design and construction of the UPS, conclusion and recommendation. ...Preview Download Preview +Other Electrical Electronics Engineering project topics and materials you might be interested in»The construction of a 2kva automatic voltage regulator (AVR)»Generation of Constant Power Supply from a DC Source»Design and construction of a digital clock with calendar»Construction of digital AC power controller»A remote controlled AC fan speed regulator using discrete integrated circuit»Remote controlled antenna»The construction of automatic voltage inverter and a battery charger»Design of 2.5kw automatic voltage regulation with seven segment display»Simple sensitive touch alarm»Construction of a car touch intruder alarm»Design and construction of 2KVA inverter»Design and construction of 5kva power inverter»Design and installation of 200 WATT solar power system»Design and construction of an automatic change over switch»Construction of a battery charger
