Experimental Study of 220 VAC Fan Performance Using a 12 VDC Battery Power Supply with a Sine Wave Invender

Abstract

The public's dependence on air conditioning devices such as conventional fans triggers the need for a reliable backup power supply system during power outages. This study explores the implementation of a 12 VDC battery-based standalone power supply system converted using a pure sine wave inverter to operate a 220 VAC fan. Through experimental methods, the focus of testing is directed at analyzing electrical characteristics, motor rotation stability, and the resulting energy conversion efficiency. The test results show that the inverter is capable of transforming direct voltage into fan voltage and can operate optimally at maximum speed with an average current consumption of 5.6 A. In addition, this system is able to maintain an operational duration of up to 1.45 hours before the battery voltage reaches the critical discharge limit. The decline in mechanical performance of the fan is proven to be insignificant compared to when using the PLN electricity grid. This research concludes that the integration of a pure sinusoidal inverter is effective in maintaining the performance of the fan induction motor from the risk of overheating and efficiency degradation due to wave distortion
