Research output: Chapter in Book/Report/Conference proceedingConference contributionScientificpeer-review


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. Short-circuit and overload states are analyze based on these simulation models.
