Abstract

A comprehensive analysis on a novel LC 3 star Buck converter is introduced in this paper. DC-DC, AC-DC and closed loop topology of the designed converter is examined. The analysis verifies the improvement done due to the implementation of the LC 3 star arrangement. Efficiency of the proposed DC-DC converter has a maximum efficiency of 96.71%. For AC-DC, maximum efficiency is 97.47%. LC 3 arrangement also improves the power and THD of the proposed AC-DC converter. To further improve the THD, a closed loop analysis is also done. Simulations are done by using PSIM software. A 10V prototype is made, which shows similar results with the theoretical analysis.
