Fault tolerant DC-DC converters in DC microgrids

2017 IEEE Second International Conference on DC Microgrids (ICDCM), 2017
The deployment of DC microgrids proves to be an excellent opportunity to significantly increment the energy efficiency in buildings. Among other components, DC-DC converters play vital functions in a DC microgrid. However, the reliability levels of these energy conversion solutions are still quite limited.

DSP-based fault detection for DC-DC converters

2015 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2015
Power electronics converter systems (PECS) are significant devices, which are used in industrial applications, including smart grids and variable speed AC drives. Therefore, the knowledge about the fault mode behavior of a converter system is extremely important from the perspective of protection and fault control in power systems.

Fault-Tolerant Strategy for a Photovoltaic DC--DC Converter

IEEE Transactions on Power Electronics, 2013
The photovoltaic (PV) technology has a small impact on the environment and is suitable for a wide range of applications. The main barrier for a more extensive implementation has been the reliability, mainly related to the power converters. According to this consideration, this paper presents an open-circuit fault diagnosis and fault-tolerant scheme for

Faults in DC Networks

2020
Understanding of dc fault characteristics is very important for designing robust protection system. This chapters presents the analytical expressions for the different types of dc faults, namely pole-to-pole (PP) and pole-to-ground (PG). Firstly, fault current calculation for current source converter (CSC)-based dc system is presented. This is followed

DC Networks Including Multiport DC/DC Converters: Fault Analysis

IEEE Transactions on Industry Applications, 2015
DC networks that include storage systems, renewable sources and Front End Converters can provide some advantages compared with AC grids. On the other hand, the interruption of fault currents is difficult due to no-zero crossing of the current. The use of traditional DC circuit breakers is not sufficient to protect power electronics switching components.

Fault Diagnosis and Fault-Tolerant Control Operation of Nonisolated DC–DC Converters

IEEE Transactions on Industry Applications, 2018
This paper proposes a fault diagnosis and identification method for nonisolated dc–dc converters. The method can detect the fault, and identify the faulty switch and the switch fault type in less than one switching cycle. The main idea is to apply the derivative of the inductor current based on the modulation of the particular dc–dc converter to ...

Open-Circuit Fault Diagnosis for Interleaved DC-DC Converters

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
Interleaved DC-DC converters are prevalent in many applications like wind turbine systems, photovoltaic energy systems, and hybrid electric vehicles, for their characteristics of high conversion efficiency and low current ripple. Motivated by the increasing requirement of system reliability, fault diagnosis and tolerant strategies for this topology ...

Fault Diagnosis and Fault-Tolerant Control for the Sensors of DC-DC Boost Converter

2018 37th Chinese Control Conference (CCC), 2018
The sensor plays a critical role for the normal operation of DC-DC Boost converter, and sensor fault is prone to cause the system shutdown. In this regard, this paper proposes a simple and effective fault diagnosis and fault-tolerant control strategy for both inductor current and output voltage sensor fault based on the Luenberger state observer.

FPGA based fault detection and fault tolerance operation in DC-DC converters

2014 International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2014
Single-ended non-isolated DC-DC converters are used in embedded and safety critical applications. In more applications like airplanes, trains, electric vehicles, ships and distributed power systems fast fault detection is a mandatory step in order to make a suitable response to a switch fault.

Integer-code DC fault dictionary

2000 IEEE International Symposium on Circuits and Systems. Emerging Technologies for the 21st Century. Proceedings (IEEE Cat No.00CH36353), 2002
This paper addresses itself to computer-aided diagnosis of analog circuits by means of simulation-before-test approach, the so called dictionary approach. New method of dictionary construction is presented. The method combines three previously presented methods, namely: sensitivity based method of finding ambiguity sets in measurement space and ...
