| dc.title | Isolated bidirectional CLLC resonant DC-DC converter for electric vehicles | en_US |
| dcterms.abstract | Nowadays, because of the increasing development of electric vehicles, V2G(Vehicle-to-Grid) technology is getting more and more attention. Bidirectional DC-DC converters play an important role in V2G, undertaking the task of bidirectional energy transfer. With the characteristics of soft switching and the consistency of forward and reverse transmission control strategies, CLLC has become an important research topic for bidirectional DC-DC converters. Therefore, this paper focuses on the symmetrical CLLC DC-DC resonant converter, including its working principles, design procedures, controls, and simulations. | en_US |
| dcterms.abstract | The symmetrical topology and working principles of the CLLC converter are explored and investigated. The fundamental equivalent model of the symmetric CLLC resonant converter is derived based on the first harmonic approximation to give the relationship between voltage gain and frequency. The calculation method is given for the voltage and current during operation using the phase quantity method. The steps of designing the resonant tank are given with constraints on two parameters, inductance ratio and quality factor. | en_US |
| dcterms.abstract | The magnetic materials for the isolated high-frequency transformers are studied and the design procedures of the isolated high-frequency transformers are presented. | en_US |
| dcterms.abstract | The circuit model and transformer model were built for simulation in Simulink and ANSYS Maxwell software respectively. | en_US |
