ABB S – 123H 3BHB030479R0512 Phase Module

The ABB S – 123H 3BHB030479R0512 is a phase module used in the ACS 6000 medium – voltage AC drive2. It features an IGCT (Integrated Gate – Commutated Thyristor) made by introducing a buffer layer and anode transparent emitter structure in the gate – turn – off thyristor (GTO) and integrating the gate – driving circuit6. This enables the IGCT to have high current – carrying capacity, high breakdown voltage, low on – state voltage drop, as well as the advantages of high switching speed and high reliability6. It is suitable for various industrial applications that require high – power and high – voltage drive, such as those in the oil and gas, mining, and metals industries2.
