A design of an Automatic Power Supply using Arduino

This study is about design of an Automatic Power Supply using Arduino. The best design for an automatic power supply is designing an Uninterruptable Power Supply system. The system is reliable and applicable to every electrical appliance because it can give a backup power supplies when the main power is fail as well as to protect the system data and electrical power instrumentation. The objective of this study is to design an Automatic Power Supply using an Arduino and to study the power quality of the system. There are 4 main components for this design which is the Arduino as the microcontroller, rectifier as the battery charger circuit, battery as a backup supply and pure sine wave inverter to convert the DC supply from the battery to AC supply and deliver it to the load. The power quality of the system can be measure and analyse by using suitable equipment such as oscilloscope to measure the harmonic distortion of the system or Fluke Recorder which can collect all the data of the system and monitor it through the Fluke analyser software. The method in this system is to design a system that can provide a backup power supply when there’s a failure in the main power supply without any time delay to avoid and to protect the equipment from damage and losses data. The design of the Automatic Power Supply is done by following all the specifications that was needed from all the research.
