Abstract:
Resonant converters are becoming increasingly popular due to their lower power loss, higher efficiency, improved electromagnetic interference (EMI) characteristics, and better bi-directional performance. To transfer power bi-directionally, it is necessary to have two resonant tanks on both the primary and secondary sides of the transformer. Two types of resonant topologies, namely, CLLC and CLLLC, are widely used in the EV sector. This paper aims to compare these two converters in terms of power loss, component count, operation, EMC behavior, volume, and efficiency. This way, the design process for two 11 kW 400 V CLLC and CLLLC converters is presented, and a comprehensive comparison is provided.
