Bi-directionally controlled thyristors
ثبت نشده
چکیده
for a better worldTM The bi-directional controlled thyristor (BCT) is a concept for high power phase control thyristors (PCTs) developed by ABB Switzerland Ltd., Semiconductors where two anti-parallel high power thyristors are integrated onto one single silicon wafer and are assembled into one housing. This feature enables designers of static VAr compensators, static switches, soft starters and motor drives to meet higher demands concerning size, reliability and cost for their end product. ABB has developed a BCT product matrix of 96 and 118 mm wafers and voltages from 2800 to 6500 volts. Application Note 5SYA 2006-03

Thyristors and Triacs Control Gate Trigger Circuits
The thyristor is a power semiconductor device with the control terminal called grid or gate (G). The device name comes from the similarity of operation with the gas triode: thiratron transistor. Because the thyristors are mainly used in the controlled rectifier structures, the technical literature calls them as SCR (Semiconductor Controlled Rectifiers) devices. After the series manufacture star...
متن کاملHither and yon: a review of bi-directional microtubule-based transport.
Active transport is critical for cellular organization and function, and impaired transport has been linked to diseases such as neuronal degeneration. Much long distance transport in cells uses opposite polarity molecular motors of the kinesin and dynein families to move cargos along microtubules. It is increasingly clear that many cargos are moved by both sets of motors, and frequently reverse...
متن کاملStructure, evolution and function of the bi-directionally transcribed iab-4/iab-8 microRNA locus in arthropods
In Drosophila melanogaster, the iab-4/iab-8 locus encodes bi-directionally transcribed microRNAs that regulate the function of flanking Hox transcription factors. We show that bi-directional transcription, temporal and spatial expression patterns and Hox regulatory function of the iab-4/iab-8 locus are conserved between fly and the beetle Tribolium castaneum. Computational predictions suggest i...
متن کاملCurrent multiplication by using multiple thyristors.
This paper presents a circuit topology to obtain current multiplication by using multiple thyristors. To gain insight into this technique, an equivalent circuit model is introduced. Proper operation of the topology was demonstrated by experiments on a small-scale setup including three thyristors. One thyristor is triggered by a trigger circuit; the other two are autotriggered and require no ext...
متن کاملJournal of the International Association for Shell and Spatial Structures: J. Iass
In this paper, we present newly explored families of rigid-foldable cylinders and the cellular structures constructed from these cylinders; the families include zonogon extrusion cells, bi-directionally flat-foldable cells, and a novel type of cells, i.e., woven cylinder cells. We show the geometry of such structures to demonstrate their validity, their parametric design method, and their kinet...
