This paper presents an analysis and design of a charging unit inside an electric vehicle extreme fast charging station. Due to the benefits that partial power processing achieves in terms of size reduction and efficiency improvement, it is decided to implement a partial power converter architecture. This type of architectures reduce the power to process by the converter but, they require an isolated topology. Therefore, a dual active bridge is selected for the study. Then, design wise, four different turns ratio values are selected and their performance results are compared in terms of processed power by the converter, semiconductors stress factor and energy loss. Finally, it is concluded that the turns ratio value is a key factor that must be correctly selected for optimizing the concerned comparison parameters. [-]
