Design and simulation of an LLC resonant voltage boost converter

Abstract

The research presents the design and simulation of an LLC resonant voltage boost converter that produces medium voltage level from low voltage level. The input of the converter is connected directly to a solar cell, and its output is also directly to a three-phase inverter, which implements an induction motor drive. The study briefly describes the operation of the LLC converter, explains in more detail the design of the values of the passive elements, and then the result of the simulation based on the designed parameters. The simulation was implemented in a MATLAB based graphical development environment (Simulink).
