Over current protection methods for LLC resonant converter

Eighteenth Annual IEEE Applied Power Electronics Conference and Exposition, 2003. APEC '03., 2004
LLC resonant converter was getting more and more attention in recent years because of its high efficiency, high frequency operation capability and simple structure. In this paper, the over current protection issue of LLC resonant converter is discussed.

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.

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.

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

Fast, configurable over-current protection for high-power modules

2015 IEEE Electric Ship Technologies Symposium (ESTS), 2015
Protection from over-current situations and the resulting risk of device failure is a requirement when testing limited-run, experimental modules. This paper demonstrates a fast, configurable, and consistent means for protecting against over-current conditions during Clamped Inductive Load (CIL) testing of 10 kV SiC MOSFET modules.

Wireless Communication Assisted Over Current Protection of Radial Distribution System

2021 5th International Conference on Trends in Electronics and Informatics (ICOEI), 2021
Loss of power experienced is mainly due to the presence of faults and unbalanced demand in transmission and distribution lines. Over current faults caused by over demand can damage the entire system. The work aims to develop an intelligent system with directional overcurrent relay to detect over current faults in the radial distribution system isolate ...

Over Current Protection for PFM Control DC-DC Converter

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2009
An over current protection method suitable for Fixed ON-time PFM (Pulse Frequency Modulation) Control DC-DC converters is proposed. It is based on inductor bottom current limiting, realized by monitoring the synchronous rectifier current and extending the OFF-phase of the main switch until it decreases to a predetermined limit, and can properly limit ...

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.

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 ...
