Design of a Control Strategy to Reduce DC Offset and Maximum HFT Current of a DAB Converter Under Open Circuit Fault in the First Active Bridge
摘要
In this work, a control strategy is proposed for a DAB converter operating under an open-circuit fault in the first active bridge. The strategy reduces both the DC offset and the maximum value of the high-frequency transformer current that arise during such faults, while maintaining regulation of the output power at its reference value. The control scheme is developed using the nonlinear feedback linearization technique and validated through simulation results.
