Comparison of converters using LLC and LCCT resonant tanks

In this paper, the circuit topologies of LLC resonant DC-DC converter and half-bridge LCCT resonant DC-DC converter are comparatively studied for different kind of applications. A comparison of efficiency, cost and behavior of these power converters is provided. Simulation models of LLC and LCCT circuits are created using magnetic and thermal models of individual components using PLECS simulation software. Based on the circuit investigation within critical operational conditions, short-circuit and overload states are analyzed.
