An Analytical Steady State Model of LCC Resonant Converter for X-ray Generator

Resonant converters operate by using the natural behavior of certain components to minimize switching losses. These converters have the Soft Switching Characteristics which reduces the stress on the devices and leads to higher efficiency. The family of hybrid resonant converters includes the advantages of series and parallel resonant converters. LCC resonant converter is a type of resonant power converter that leverages a combination of series and parallel resonant elements to achieve soft switching and improved efficiency in high-frequency power supply applications. In this work, LCC resonant converter is simulated in open loop and closed loop with PID controller and fuzzy logic controller. The Converter is studied for operation in different modes and state Space Modeling is done. Transfer Function is obtained for the modeled converter. The converter is also examined for stability with location of poles and zeros in root locus and Bode plot. Entire software analysis is done in MATLAB Simulink.
