FAULT IDENTIFICATION AND MITIGATION FOR THE DUAL INPUT FAULT TOLERANT DC-DC CONVERTER FOR DC MICROGRID

This work introduces an improved methodology for detecting the fault in the MOSFET switch used in the dual input fault tolerant (DIFT) DC-DC converter for DC microgrid application. The converter uses both photovoltaic (PV) and fuel cell (FC) sources to make sure that power is constantly available to load.

DC-DC converter fault diagnostic in PV system

2017 International Conference on Green Energy Conversion Systems (GECS), 2017
The photovoltaic (PV) system productivity is a decisive factor. To achieve a high productivity, the system availability should be checked. So even under a faulty situation, the system should operate continuously. As a proposed solution, the fault tolerant control (FTC) is recommended.

DC arc fault: Characteristic study and fault recognition

2011 1st International Conference on Electric Power Equipment - Switching Technology, 2011
DC arc fault introduces major safety concerns in a wide variety of power electronic applications. However, the randomness and instability of dc arc makes it difficult to be detected. In this paper, an experimental system to study the characteristics of series dc arc is designed and different tests were conducted in order to determine the influence of ...

The Fault Analysis of PV Cable Fault in DC Microgrids

IEEE Transactions on Energy Conversion, 2019
Compared to the AC microgrids, the advantages of DC microgrids are notable. However, the development of DC microgrids is being constrained by the lack of mature protection schemes. For the foundation of designing protection schemes, the existing fault analysis focused on the fault characteristics of voltage source converters and ignored other ...
