Industrial Fieldbus Improvements in Power Distribution and Conducted Noise Immunity With No Extra Costs [PDF]

open access: yes, 2011
Industrial distributed control continues the move toward networks at all levels. At lower levels, control networks provide flexibility, reliability, and low cost, although perhaps the simplest but most important advantage is the reduced volume of ...

DC fault isolation study of bidirectional dual active bridge DC/DC converter for DC transmission grid application [PDF]

open access: yes, 2015
Fast isolation and detection of DC faults is currently a limiting factor in high power DC transmission grid development. Recent research has shown that the role of DC/DC converters is becoming increasingly important in solving various DC grid challenges ...

Protection strategy for multi-terminal DC networks with fault current blocking capability of converters [PDF]

open access: yes, 2017
High voltage dc networks are a promising technology to flexibly transmit power over long distances. However, dc grid protection is still a major challenge. DC fault clearance can be mainly achieved with three devices. These are ac circuit breakers (ACCBs)

Impact of maximum back-EMF limits on the performance characteristics of interior permanent magnet synchronous machines [PDF]

open access: yes, 2006
Interior permanent magnet (IPM) synchronous machines are vulnerable to uncontrolled generator (UCG) faults at high speed that can damage the inverter. One approach to reducing this risk is to impose limits on the maximum machine back-EMF voltage at top ...
