Aging of the over-voltage protection components
2002 23rd International Conference on Microelectronics. Proceedings (Cat. No.02TH8595), 2003 The aim of this work was to examine the influence of the number of activations, i.e. over-voltage pulses, on the aging of over-voltage protection elements. Both nonlinear (gas-filled surge arresters (GFSA), varistors, over-voltage diodes), and linear (capacitors-constituents of filters) over-voltage protection elements were tested. The instruments used

Implementation of protection circuit for over voltage and under voltage protection
Materials Today: Proceedings, 2021Abstract This paper identifies the development of an under voltage and over voltage protection in order to avoid damage in load side. Most of the industries and as well as home appliances are very expensive also more sensitive. This may get damaged due to the instabilities in ac mains supply.

The Innovative Method for Determining Characteristics of Over-Voltage Protection Elements
2006 25th International Conference on Microelectronics, 2006 This paper presents an innovative method for efficient characterization of relevant characteristics of non-linear over-voltage protection elements in low-voltage applications. Standard measuring equipment is modified to enable an efficient and repeatable experimental procedure to investigate characteristics of over-voltage diodes and varistors: volt ...

Aging of the over-voltage protection elements caused by over-voltages
Microelectronics Reliability, 2002The aim of this work is examining the influence of the number of the activation––over-voltage pulses to the aging of over-voltage protection elements. Both non-linear (gas-filled surge arresters (GFSA), varistors, over-voltage diodes) and linear (capacitors––constituents of filters) over-voltage protection elements were tested. The instruments employed

An over-voltage protection circuit for CMOS power amplifiers
2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008With increasing demand for higher integration and lower cost of mobile communication devices there is a growing trend towards the use of CMOS power amplifiers (PAs) instead of GaAs or SiGe PAs. Although being comparatively inexpensive, CMOS not only suffers from inferior RF performance but also from low breakdown voltages. This gets an issue especially

Over-Voltage Protection Epoxy-CNT Composites
2019 International Conference on Electronics Packaging (ICEP), 2019The electronics industry is always looking for new ways of protecting devices from over-voltage, or over-current scenarios. In the present work we will introduce novel low-voltage epoxy-carbon nanotube composites with high non-linearity values in resistive devices. Some of the non-linearities achieved had alpha values greater than 10.

Characteristic Prediction of a Varistor in Over-Voltage Protection Application
2014This paper presents a characteristic prediction of a varistor for modeling a varistor in over-voltage protection applications. Variable resistor (Varistor) is one of common devices to protect following electric devices from over-voltage. However, the principle of varistor is still unclear due to its non-linear characteristics between amount of voltage ...

Transient over-voltage protection in distributed generators systems
2016 IEEE Smart Energy Grid Engineering (SEGE), 2016In distributed generators systems (DGs), islanding condition occurs when generators continue to energize a part of the power network while the main utility power is no longer available. In such situations, transient over-voltage condition might occur when the amount of generated power exceeds the load consumption and hence needs to be mitigated.

Design thinking for innovation in 3D VR Over-Voltage Protection with Memristor
2020 11th IEEE International Conference on Cognitive Infocommunications (CogInfoCom), 2020This paper shows an example of CogInfoCom as during analyses the operation of a memristor in a real 3D VR based teaching. This paper looks at the possibility of the application of a macroscopic memristor (MR), not yet available, combined with a spark gap for over-voltage protection purposes.
