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

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 ...

A Compact Over-Voltage Protection Circuit for HBT Power Amplifiers
2006 IEEE MTT-S International Microwave Symposium Digest, 2006This paper presents an over-voltage protection circuit with low capacitance loading and small size. Its operation principles and measured performance will be presented. As a case study, a 5.4-6.0 GHz InGaP/GaAs HBT power amplifier with this compact over-voltage protection circuit, resulting in no degradation in PA performance, is demonstrated.

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.

Protection of Supervisory Control Lines Against Over-Voltage
Transactions of the American Institute of Electrical Engineers, 1928Supervisory control lines used in the remtote or automatic control of electric plants are subject to overvoltages dangerous to insulation and to operators. These overvoltages may be caused by lightning, crosses with the power lines, or induction from them.

Under Voltage and Over Voltage Monitor to Protect the Electrical Load
2019 IEEE PES/IAS PowerAfrica, 2019This research paper is presented to design a system that will monitor and protects the electrical loads from under voltage and over voltage supply, which may be due to unforeseen adverse effects of electrical voltages or voltage fluctuations. These adverse effects of voltage will affect the power quality that is being supplied to the electrical loads ...

An Over Voltage Protection Circuit for Series Regulator Power Supplies
IETE Journal of Education, 1975AbstractAn over voltage protection circuit that protects the load from over voltages, in case of series transistor failure in a series regulator is discussed here. If the series transistor gets open between collector and emitter terminals, output becomes zero. In case of a short this circuit comes into action and makes the output voltage fall to zero.
