Reliability Enhancement of Power IGBTs under Short-Circuit Fault Condition Using Short-Circuit Current Limiting-Based Technique

A Comprehensive Mathematical Model for Analysis of WR-Resolvers under Stator Short Circuit Fault

Wound-Rotor (WR) resolvers are the most widely used position sensors in applications with harsh environmental conditions. However, their performance is exposed to failure due to the high risk of short circuit (SC) fault. Although the output current of the resolver is negligible, its thin copper wires increase the probability of the short circuit fault. To avoid the propagation of the turn-to-tu...

Decreasing Distribution Generation Effects on Grid Short Circuit Level Using Superconducting Fault Current Limiter Through Updating Relays Set-Points

Power system protection at transmission and distribution levels based on overcurrent relays is essential based on their properties such as detection, stability, high speed, backup and error correction accuracy. Since distributed generation sources are connected to the power grid, they not only increase the short circuit level of the grid, but also disrupt the set point of main and backup relays...

Short-Circuit Current Modeling for CMOS Standard Cells Power Characterization

Short-circuit currents contribute signiicantly to the total power consumption of CMOS circuits. In this paper we describe a procedure to characterize libraries of standard cells in order to extract information on the power dissipation to be used later in logic-level simulators. Ours is a black box approach in which cells are characterized without looking at the internal nodes. The objective is ...

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...
