Abstract: This paper discusses the design and prototype implementation of a multi-powered uninterruptible power supply system using a microcontroller. The system consisted of three basic units: the battery charging unit, the automatic switching unit and the inverter unit. The battery charging unit has components such as AC power, solar panel, a battery and the charging circuitry. The automatic switching unit includes the micro-controller and MOSFET switches to regulate the charging from multiple sources as well as switching from the power supply from AC to battery and vice versa. The inverter unit includes the transformers and other power electronic components to convert DC to AC power. Voltage and current measurement of our power supply output indicate optimal performance within expectation. Also, the battery charged faster with AC than solar power. We intend to further explore the use of miniaturized components to make the entire system smaller.
