Open-circuit switch fault tolerant wind energy conversion system based on six/five-leg reconfigurable converter

“…For open-circuit switch fault detection, the method of [16,17] is used throughout this study. In this method, fault in each leg is diagnosed by comparing the measured and estimated pole voltages.…”

“…A sliding mode observer is used for fault detection in the multicell converter presented in [15]. A very fast FPGA-based fault detection using a "time and voltage criterion" is presented in [16,17]. It is capable of detecting the fault and its location in a few tens of microseconds.…”

Fast detection of open-switch fault in cascaded H-Bridge multilevel converter

“…For short-circuit switch faults, normally using fast acting fuses the converter topology will become similar to that after an open-switch fault [24], or special supplementary hardware is needed to detect the fault, as the software methods are not fast enough to detect the short-circuit switch faults. It is also worth to mention that many drivers have the possibility to identify the short circuited switches and stop the operation [26,27]. Nonetheless, this is not in the scope of this paper.…”

Advances in Electrical Machine, Power Electronic, and Drive Condition Monitoring and Fault Detection: State of the Art

“…Although most of the works in the power converter FD area address ac-dc or ac-ac converters, an increasing number of recent papers are focused on FD in dc-dc converters [78].…”
