Overvoltage Protection Circuits for Ultrasonically Powered Implantable Microsystems
Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2019This paper presents a novel overvoltage protection technique for ultrasonically powered microsystems. The proposed idea benefits from voltage-current characteristics of the piezoelectric harvesters, and limits the amplitude of the harvested signal by ...

Overvoltage Protection of Sensitive Consumers in DC- Powered Industrial Rail Grid
2019 11th Electrical Engineering Faculty Conference (BulEF), 2019This article explores problems related to the electrical supply of inverters for the own needs of mine engine. In such grids exist overvoltage with great energy leading to damage of mining locomotive's inverter for own power supply.

Investigation of SPICE Models for Overvoltage Protection Devices With Respect to Fast Transients
IEEE Letters on Electromagnetic Compatibility Practice and Applications, 2018Models of overvoltage protection devices, such as transient voltage suppressor diodes (TVS-diodes) are largely available in circuit analyzer tools. For this letter, the widely used circuit simulation tool LTspice was employed and during the course of ...

Overvoltage protection of capacitor banks
2011 International Symposium on Lightning Protection, 2011The application and effectiveness of MO surge arresters to capacitor banks is discussed. Principle application rules for different configurations are given. The influence of MO arresters with different ratings on voltage and current at the capacitors and at a re-striking circuit breaker respectively is shown and quantified.

Thyristors with overvoltage self-protection
1981 International Electron Devices Meeting, 1981Power thyristors which are immune to destructive triggering by overvoltage transients have been designed, fabricated, and tested. A 10- mil deep well was etched in the gate region prior to the final p-type diffusion. This modified the forward blocking junction so that it avalanched at 2800V.

Impact of line length on the operation of overvoltage protection in LV networks
Electric Power Systems Research, 2015 This paper deals with analysing the impact of LV lines impedance on the operation of overvoltage protection, especially on the operation of gas discharge arresters. A model of the overvoltage protection with all elements (gas discharge arrester and metal-
