Abstract

Power electronics engineering nowadays gaining attention such example advantage of small components that can produce large benefits in quality of power production. If the circuit is designed to take into account all possible advantages and disadvantages of a parameter, it can have an impact on the resulting product. Structured circuit LED power previously divided into two stages, single stage and two stage structures has been in formation by previous researchers for the development of power electronics areas. Converter is a device that converting the unregulated DC input to a controlled DC output with a desired voltage. The applications that use the converter is switched-mode power supply (SMPS), DC motor control and battery charges. Two major sections that will analyse are non-isolated DC-DC converter and isolated DC-DC converter. Whereas in this project there is a combination between the use of isolated and non-isolated. The main purpose of this project is produced to meet the objectives of producing AC-DC converter that is capable of producing large scale power and is suitable for all current applications. Experiment was conducted to test whether the three circuits can meet the conditions of producing large power output and efficiency of the best circuits. Tested power output circuit by selecting 36W power LEDs connected in series based on LED configuration. Calculations have been performed to identify products capable of meeting the specified requirements. Analysis done by using Matlab Simulink software versions R2010a. The output voltage should produce 24V. Among all the circuits, the best circuit performance is interleaved single-stage flyback converter. The results of the analysis carried out, total harmonics distortion value is 15.94% and the efficiency of the circuit is 15.07%.
