Over-Current Protection for Power Packet Dispatching System

IEEE Transactions on Circuits and Systems II: Express Briefs, 2020
Power packet dispatching system (PPDS) which integrates information into power distribution has been proposed recently. A PPDS distributes power in a packet form to the loads. It offers reduced power processing stages and smart power handling according to load demand and power generation capacity.

Adaptive Over-current Protection Algorithm for a Microgrid

2018 IEEE 13th International Conference on Industrial and Information Systems (ICIIS), 2018
In this paper, a modified protection scheme is proposed for connecting distributed generation to the utility grid. This is based on Adaptive Overcurrent Protection (AOP) scheme proposed in literature but is modified to suit all the possible needs of a microgrid. The main objective of this algorithm is to protect the entire system (including distributed

Design of over-current protection circuit for power transistors

2016 IEEE International Conference on Consumer Electronics-Taiwan (ICCE-TW), 2016
The paper presents an over-current protection circuit designed for high voltage power switches. The proposed protection mechanism employs a current limiter to monitor the current flowing through the power switch. The current limiter protects the power switch from potential damage by automatically switching off the device once the current exceeds the ...

DC GRIDS: New over current protection

2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016
Fuses and Circuit Breakers play an important safety role in electrical transportation systems. Challenging new applications, especially in DC grids, 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.

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 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.
