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.

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

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.

Aging of the over-voltage protection components
2002 23rd International Conference on Microelectronics. Proceedings (Cat. No.02TH8595), 2003The 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

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.

The Over-voltage protection Of wind turbine generators
2009 World Non-Grid-Connected Wind Power and Energy Conference, 2009The paper introduces the related characteristics of wind turbine generators, Such as the wind turbine generator may cause serious over-voltage problems of electromagnetic compatibility for using converter technique and be struck by lightning easily and also result in high maintenance costs.

Integrated Over Voltage Protection Circuits for Power Transistors
2006 IEEE International Symposium on Power Semiconductor Devices & IC's, 2006Nowadays, MOSFET and IGBT power components are widely used in medium and high power converters. They are subjected to increasing requirements: electrical performances, simple implementation, reliability, integration, smaller volume and price. Moreover, their integration process offers the possibility to reduce or eliminate the need for pick and place ...

Over Voltage Protection Device Based on Multi-Strategy
Key Engineering Materials, 2011Strong electromagnetic interference occurs when the locomotive was running. Therefore, measurement errors resulted from interference exist when monitoring the rail potential only at single point. This will lead to misoperation of the protection device. An over voltage protection device based on multipoint and multi-strategy was designed.
