Abstract :
This paper proposes a new ZVZCS DC-DC converter topologies with modified resonant (CLLC-L & CLL-L) and using with the auxiliary cell are presented in this paper. The proposed converter topologies have ZVS and ZCS soft-switching features. In addition to this the proposed converters feature in high order resonance with improved the overall voltage conversion gain. The soft-switched half bridge and full bridge topologies using medium frequency transformer for traction applications is presented in this paper. The major advantages of proposed topologies are able to increase the switching frequency with reduced switching losses. The detailed operation principles, state space analysis and simulations results are presented.
