“…The other active bridge of the converter can be used to control the fault current. The authors in [10][11] proposed rapid fault detection by monitoring sudden changes in the AC voltages and use this information to turn off the gate signals to the switches. The fault ride through method is integrated in the control by setting the saturation limit of maximum current reference.…”

“…The fault ride through method is integrated in the control by setting the saturation limit of maximum current reference. In [12], similar investigation as [10] was carried out by detecting the AC voltage of the converter but the authors use four-step open circuit diagnosis to trigger an active phase shift control system to locate the fault. For multi-terminal DC application, the authors in [13] proposed handshaking method to locate and isolate faulted DC line without any communication.…”

“…Authors in [9] have demonstrated that this DC offset can be controlled by phase shift (PS) angle control. Another method to overcome DC offset is to connect two coupling capacitor in series with the primary and secondary windings [10] but this method uses additional passive device in the AC circuit which can cause additional failure to the converter. The authors in [10] also addressed the DAB converter performance when a fault happened in the switches.…”

This paper presents DC fault analysis for a dual active bridge DC/DC converter which comprises of two active bridges and an internal medium frequency transformer. This topology provides galvanic isolation, voltage step up/down and bidirectional power transfer. The DC fault study assumes the DC terminal voltage of the converter is at zero. The steady state fault current is limited to a low magnitude which is less than the rated value without any controller action depending on the design of the converter. The DC faults current magnitudes are analyzed with AC equivalent circuit where only the fundamental component of the AC voltages and inductor current are considered. Phase shift and AC voltage magnitude modulation control methods are selected. A detailed dual active bridge DC/DC converter 3 MW, 4/40 kV based system is simulated using MATLAB/Simulink to validate the proposed analytical study. Further, hardware testing is conducted to confirm the DC fault studies with a 500 W 24/100 V prototype.

Failures in power semiconductors of a dual active bridge converter are characterised considering open-circuit faults in diodes and transistors. A detailed electrical waveforms analysis to identify the main symptoms of the converter during normal and failure conditions is presented. Based on this analysis, a fault diagnosis strategy is proposed which is able to identify failures either in a diode or in a transistor as well as its location in the circuit. Finally, simulation and experimental results, using a prototype of 1 KW, are presented in this study to demonstrate the practical feasibility of the theoretical proposal.
