ANALYSIS OF AN INTEGRATED PFC INDUCTOR AND RESONANT TRANSFORMER BASED ON MAGNETIC MODELING MEAS SARAN Advised by Prof. Kim, Eun Soo A thesis submitted to Jeonju University in partial fulfillment of the requirements for the degree of Master of Science Department of Electrical and Electronics Engineering Graduate School of Engineering Jeonju, University Feb 2013 ABSTRACT
This paper describes the design and analysis of an integrated transformer comprising of two different power cores- the PFC inductor and the LLC resonant transformer magnetic core. The equivalent magnetic circuit modeling approach is employed to analyze the variations in coupling coefficient and self-inductance in terms of air gaps under the operations of the respective power cores. Simulations and experimental studies were performed with the fabricated integrated transformer prototype and the results were discussed. In recent years, the demand for highly regulated and reliable power supplies with the desired smaller size, lighter weight and high efficiency in power electronics system has increased. The magnetic components are usually higher and heavier than other components on the circuit-boards. The answer for both miniaturization and material performance can be planar core technology. Therefore, the planar core was selected for 2-in-1 transformer design in this paper.
