A novel over-voltage protection method for 600V SPIC
Journal of Electronics (China), 2002A novel over-voltage protection method for 600V SPIC (Smart Power IC) is proposed in this paper. The combining FFLRs (Floating Field Limiting Rings) system is designed to be a voltage detector. The detector’s voltage can turn off the switch of the APFC (Active Power Factor Correction) circuit and the bus voltage would fall from 600VDC to 300VDC, so the

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.

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.

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 ...

Over-voltage Protection for an X-ray Therapy Tube
The British Journal of Radiology, 1945Owing to the wartime shortage of X-ray tubes, any device which is likely to lead to longer tubelife will probably be of interest to other users of X-ray tubes. Tube life is dependent upon a variety of factors, of which the most important is the running voltage of the tube.

Digest of Technical Papers. Tenth IEEE International Pulsed Power Conference, 2002
The aim of this work is the examination of the over-voltage protection under the influence of ionizing radiation. The use of modern electronic devices (nuclear, military and space technology) in the conditions of ionizing radiation brings up the question of radioactive resistance of electronic components and over-voltage protection components.
