This paper accentuates the study of LLC resonant converter by a comparative analysis of the properties of LLC resonant and pulse width modulation direct current-direct current converters.Lately, LLC resonant converters have become more appealing and desirable in many applications than other pulse width modulation converters (e.g., Buck, Boost, Cuk) for their soft-switching techniques like zero voltage switching, zero current switching as well as low electromagnetic interference.This paper presents Handle Set;Sleeve an analysis of efficiency variation, output voltage’s ripple, and various transient performances like percentage overshoot, and the settling time with the variation of load current in a comparative way between LLC resonant converter’s buck, boost operation, and conventional pulse width modulation converter’s buck, boost operation.

Feedback proportional-integral-derivative duty cycle controller is used in all converter topologies for some specific analysis.A fixed input voltage of 100 V is selected for simulation and an output voltage of QUINOA PUFFS 24 V for buck operation and 120 V for boost operation are chosen.For simulation purposes, MATLAB/SIMULINK software is used.
