A Time-Domain Based APP Designer For Resonant Converters With GUI Features

摘要

A novel and high fidelity simulation-design tool has been proposed for optimizing the design of DC-DC resonant converters. The design tool uses a generalized time-domain analysis applicable to multiple resonant tank configurations. This tool has been made using a MATLAB app designer. The main features of this tool are as follow: 1) fast and accurate steady-state analysis, 2) user-friendly GUI features, 3) design curves for performance optimization and 4) state-of-the-art design examples. The tool is demonstrated for following wide-range DC-DC applications: 1) Solar PV DC-DC micro-inverter 2) Data Center 48V to 12V DC-DC 3) Front-end DC-DC application using LLC and CLL resonant tanks. A comparative analysis is shown between LLC and CLL resonant tanks using design curves. Experimentation has been done to verify the theoretical findings from this tool on the 320W prototype.
