Threshold selection for the over current protection function

CAS 2011 Proceedings (2011 International Semiconductor Conference), 2011
This paper proposes an over current protection circuit implementation with a new selectable threshold level function. The over current threshold level is controlled from a dedicated pin by an external resistance. A circuit capable of providing a reference current proportional to the external con-trol resistor is designed.

Characterisation of a motor driver with over-current protection and speed feedback

The 5th International Conference on Automation, Robotics and Applications, 2011
Urban search and rescue robots are becoming more prolific and widely used. However, these robots are still being developed for specific environments and situations. The research being undertaken at Massey University is part of a larger collaboration to produce a multi-tiered robotic system for urban search and rescue. The first major hurdle of a mobile

A novel over-current protection for digital power amplifier

2012 IEEE 11th International Conference on Solid-State and Integrated Circuit Technology, 2012
The paper presents a novel over current protection circuit in digital power amplifier. The over current protection circuit would be used to shut down the output buffer when two output pins short-circuit to power supply, short-circuit to ground or short-circuit to each other.

A new IGBT with a monolithic over-current protection circuit

Proceedings of the 6th International Symposium on Power Semiconductor Devices and Ics, 2002
A new IGBT structure with a monolithic overcurrent sensing and protection circuit has been developed. The feature of this device is a novel integration of a sensing and protection circuit which consists of a sensing IGBT, lateral n-MOSFET, polycrystalline silicon diode and resistor with an IGBT structure.

Tuned Fuzzy Controller Based Over Current Protection Scheme

2008 Joint International Conference on Power System Technology and IEEE Power India Conference, 2008
The measurands from the remote location are gathered at central control room (CCR) for processing, taking corrective action and presenting to higher hierarchy in a presentable format and it requires remote terminal unit to communicate between them. The pre-processing of current has been done using fuzzy logic algorithm for pre-processing the measurands

Intelligent over-current protection scheme in inverter-based microgrids

2015 Smart Grid Conference (SGC), 2015
Recently by technological developments in inverterbased devices, application of these prominent apparatus has gained more attention in newly emerged microgrids (MGs). In this paradigm, the concept of multiple inverter-interfaced distributed generations (IIDGs)-based MG is now a reputable term.

New over current protection technology addressing DC Transportation

2016 IEEE Transportation Electrification Conference and Expo (ITEC), 2016
Fuses and Circuit Breakers play an important safety role in electrical transportation systems. Challenging new applications, especially in DC, have brought conventional current limiting devices to their limits. Indeed, mechanical circuit breakers may be too slow to open for networks with large DC fault currents. On the other hand, fuses may be too slow

Adaptive over current protection for distribution feeders with distributed generators

IEEE PES Power Systems Conference and Exposition, 2004., 2005
The connection of distributed generators (DG) to distribution networks influences the performance of the networks. This paper focuses on the impact of DG on the feeder protection, specifically the impact on the overcurrent (OC) relay performance. The paper presents simulation results to show the extent of deterioration a DG can cause on the OC relay ...

Fast over-current protection of high power IGBT modules

2005 European Conference on Power Electronics and Applications, 2005
IGBT high power modules are protected against over-current and short-circuit. These phenomena are defined and classical methods are explained. A new protection circuit is presented with the help of a formal approach for enhanced response time.
