Black-Start Strategy for Three-Phase Dual Active Bridge Converter Based on Buck and Phase-Shift Control
摘要
Abstract
As the key component of the DC microgrids,the performance of high-power bidirectional isolated DC-DC converters has a significant impact on the microgrid operation.When the microgrid starts and recovers after fault occurrence,the isolated DC-DC converter often generates a huge inrush current,which brings a great challenge to the system reliability.To address this issue,this paper presents a soft start method for a three-phase dual active bridge converter by combining the Buck mode with phase-shift control,which can greatly reduce the start-up inrush current.Besides,the output voltage regulator is also designed with the load current feedforward function,and the improved instantaneous current control is employed in the transient state,so that the phase shift angle will change smoothly.The simulation results finally confirm that this method can greatly reduce the inrush current and improve the dynamic performance in the black startup.关键词
