A Novel High Frequency-Link Bidirectional DC- DC Converter for Electric Vehicle Applications

In this study, a novel high frequency-link bidirectional DC-DC converter is proposed as part of electric vehicle (EV) to achieve bidirectional power flow: grid-to-vehicle (G2V) and vehicle-to-grid (V2G). The use of high frequency transformer (HFT) in the system not only increases the system efficiency, but also reduces the filter component size and dimensions. Furthermore, the transformer has been designed to operate in various conversion rates through the transformer selective pins. To verify the performance of the converter, simulation studies have been performed through Matlab/Simulink software.
