Power electronics converter systems (PECS) are significant corner stones in enormous variety of industrial applications, including smart grids and variable speed drives. One of the factors that assist to improve such systems is the study of their fault mode behaviors. Besides that, the open circuit (O-C) faults in the PECS do not trigger the standard protection systems in the converter but rather...
Reliability of power electronic systems is of paramount importance in industrial, commercial, aerospace, and military applications. Faults in power converters are classified as short circuit faults, open circuit faults, and degradation faults. Short circuits (S-C) in most cases cause an overcurrent condition that is readily detected and acted upon by standard protection systems. However, open circuit...
The monitoring and supervision of grid-connected solar and wind energy sources with consumers require further improvement of the performance and the stability of energy transfer. Therefore, the effective communication between the power generation and the supervisory nodes of power grids are necessary to manage electrical generation from renewable energy sources. The communication interface, which...
This paper presents a fault detection, classification, and diagnoses for all the successive stages of the power electronic converter, including; the three phase rectifier, the dc-dc converter, and finally the single phase inverter. The paper provides a number of proposed algorithms for the open circuit fault diagnoses of these stages. The inputs of these algorithms are the voltage and current measurements...
