Electrum AV, CJSC is an enterprise that specializes in the development and production of semiconductor devices of modular build power electronics, control devices and integrated systems of power electronics for use in industrial and military uses.
The nomenclature of “Electrum AV” can be divided by four big groups: specialized control circuits, i.e. drivers; power diode, thyristor and transistor modules (including the small rectifier bridges modules); power modules with built-in control and power blocks that are complete products containing both the power modules and the specialized control circuits.
The control circuits – this is, first of all, the control drivers IGBT or MOSFET-transistors. The products are intended to control and protect transistors with a field control. Transistor drivers are manufactured in different designs; the drivers can be installed directly to the power module, they can be installed remotely or can be soldered to the PCB. The transistor drivers have output current up to 48 A, average output power – up to 8 W and they can operate at frequency up to 200 kHz. Control transistor parameters: breakdown voltage up to 6500 V, collector current up to 2000 A.
The power modules – this is transistor, thyristor, thyristor-diode and diode modules. The diode modules, depending on the type of used diodes, can be based on fast-recovery diodes, Schottky diodes or rectifying diodes; the last one is installed in pair with thyristors. The transistor diodes are also divided by type of the used transistor: either MOSFET-transistors, or IGBT-transistors. The first ones are intended to operate in rectifiers with peak voltage up to 200 V, the second ones – from 600 V to 6500 V.
