Fault-Tolerant Control Strategy for Sub-Modules Open-Circuit Fault of Modular Multilevel Converter

Fault Diagnosis and Fault-Tolerant SVPWM Technique of Six-phase Converter under Open-Switch Fault

In this paper, a new open-switch fault diagnosis method is proposed for the six-phase AC-DC converter based on the difference between the phase current and the corresponding reference using an adaptive threshold. The open-switch faults are detected without any additional equipment and complicated calculations, since the proposed fault detection method is integrated with the controller required ...

A New Circuit Topology for Open Circuit and Short Circuit Fault Tolerant Dc - Dc Converter

This paper describes a new design for a fault tolerant Hbridge dc-dc converter. Open circuit and short circuit fault tolerance is achieved using multilevel converter topology in combination with pulse width modulation control strategy allowing a large set of converter switching states to produce bidirectional power flows at any required output voltage. If two switches fail at particular instant...

A Fault Tolerant Voter Circuit for Triple Modular Redundant System

Defect rate in Nanoelectronics is much higher than conventional CMOS circuits. Hardware redundancy can be a suitable solution for fault tolerance in nano level. A voter circuit is a part of a redundancy based fault tolerant system that enables a system to continue operating properly in the event of one or more faults within its components. Robustness of the voter circuit defines the reliability...

Fault Tolerant Control Strategy for OmniKity-III

In this paper OmniKity-III (OK-III), a novel wheeled omni-directional mobile robot is developed and its kinematic model and control laws are derived. A special gear train was developed to have omnidirectional mechanism using conventional tire wheels. Several control laws are provided by considering the robot as a redundantly actuated wheeled mobile robot (WMR) on the plane. Since the robot has ...
