The aluminium based selenium rectifier elements are manufactured by an improved, closely controlled vaccum deposition process. This new process ensure stable, non- ageing, low loss characteristics permitting higher current density operation while maintaining a reliability standard which has been a by in the selenium rectifier field for over thirty years.
INSEL Rectifiers India Thyristors may also be necessary to act in the opening switch mode as well. Such applications may contain those where voltage is reapplied to the pulse power switch shortly after closing and the switch needs to have improved blocking capability or the transfer energy needs to be controlled.
Bridge Rectifier A bridge rectifier makes use of four diodes in a bridge arrangement to achieve full-wave rectification. This is a widely used configuration, both with individual diodes wired as shown and with single component bridges where the diode bridge is wired internally.
Rectifiers An electrical circuit used to convert AC into DC current. A rectifier is a diode that causes the current to flow in only one direction. The output of the rectifier is essentially half-AC current, which is then filtered into DC.
Isolating transformer are used in air field lighting system and provide isolation between the primary high voltage series circuit and low voltage secondary circuit. The primary of all transformers are connected in series and fed by constant current regulator. Secondary feeds the individual airport runway light.
