Efficiency and Cost Optimization of Dual Active Bridge Converter for 350kW DC Fast Chargers
<|reference_start|>Efficiency and Cost Optimization of Dual Active Bridge Converter for 350kW DC Fast Chargers: This study focuses on optimizing the design parameters of a Dual Active Bridge (DAB) converter for use in 350 kW DC fast chargers, emphasizing the balance between efficiency and cost. Addressing the observed gaps in existing high-power application research, it introduces an optimization framework to evaluate critical design parameters,number of converter modules, switching frequency, and transformer turns ratio,within a broad operational voltage range. The analysis identifies an optimal configuration that achieves over 95% efficiency at rated power across a wide output voltage range, comprising seven 50 kW DAB converters with a switching frequency of 30 kHz, and a transformer turns ratio of 0.9.<|reference_end|>
