Electrical Characteristics of Industry’s first commercially available 1200 V rated SiC Schottky rectifiers, specially designed for operation at ≥ 250 °C are presented. These high-temperature SiC rectifiers fabricated in 1, 5, and 20 A current ratings feature reverse leakage currents of < 3 mA/cm at 1200 V up to temperatures as high as 300 °C. GeneSiC’s 1200 V/20A High Temperature Schottky (desi...

Aircraft electrification requires reliable, power-dense, high-efficient, and bidirectional rectifiers to improve the overall performance of existing aircrafts. Thus, traditional bulky passive must be substituted by active rectifiers, satisfying requirements imposed up-to-date standards. However, several challenges are found in terms power controllability, due standardized rectifier-based operat...

To mitigate the radio-frequency (RF) performance degradation caused by electrostatic discharge (ESD) protection device, low capacitance (low-C) design on ESD protection device is a solution. With the smaller layout area and small parasitic capacitance under the same ESD robustness, silicon-controlled rectifier (SCR) device has been used as an effective on-chip ESD protection device in RF ICs. I...

The performance of high-power converters employing silicon controlled rectifiers (SCRs) operating at several kilovolts and switching several thousands of amperes is strongly dependent on the triggering circuit and the protecting circuit (snubber) used. In this paper two standalone trigger circuit topologies are discussed and test results are given for one of them in particular, built with off-t...

Intracellular microelectrode recordings and a two-electrode voltage clamp have been used to characterize the current carried by inward rectifying K+ channels of stomatal guard cells from the broadbean, Vicia faba L. Superficially, the current displayed many features common to inward rectifiers of neuromuscular and egg cell membranes. In millimolar external K+ concentrations (Ko+), it activated ...

As per the industrial needs, regulated dc voltage with linear transfer characteristics is important in many applications such as dc magnet power supplies in a beam line system. To accomplish this motto, cosine control firing scheme is suggested to get the output voltage which is proportional to control voltage. Present paper deals with design and implementation of cosine control firing scheme f...

2014 Narrow nuclear resonances, initially used to calibrate the energy of the Birmingham Radiation Centre 3MV Dynamitron, have proved useful in discovering and identifying accelerator fault conditions. Short-term energy stability (over e few minutes) of a few tens of eV is common. However, variations of many kV occur for several days before the failure of a thermionic rectifier. The beam energy...
