DESIGN AND CONSTRUCTION OF SWITCHING MODE POWER SUPPLY(SMPS) USING FLYBACK TOPOLOGY SWITCHING MODE POWER SUPPLY(SMPS) USING FLYBACK TOPOLOGY

Abstract

In this research, a power supply has been developed using the Switching Mode Power Supply (SMPS) method as a replacement for a linear power supply. The advantage of a Switching Mode Power Supply (SMPS) is that it has smaller dimensions and is lighter and has higher efficiency than a Linear Power Supply. Research was carried out at the Electrical Engineering Education LAB in three stages, namely tool design, tool assembly and tool testing. To determine the characteristics of the Switching Mode Power Supply (SMPS), the tool was tested in the form of measuring voltage, current and frequency (input & output) with 60 trials divided into 6 stages and the resulting data was 214.8V, 0.09A, 50.5Hz for input and 13.17V, 0.97A, 269.8KHz. Then a test was carried out to find out how much influence the output frequency had on the output voltage and the test results using SPSS version 29 showed no influence of the output frequency on the output voltage.
