Multichip Thyristor - developed in
cooperation with ABB Switzerland

Purpose

The developed semiconductor switches, i.e. the Multichip Thyristors, can be used for:

Compact pin-gate-unit for the Multichip Thyristor, constructed partly in SMD technology

Characteristic values of the Multichip Thyristor:

Skills

• Development of compact semiconductor switches
• Metrology of high currents and voltages
• Circuitry development for gate units
• Construction of compact pulsed power units.
