IGBT Modules. Semikron SEMITRANS Modules

A new low-inductance 1200V IGBT module series, for use in AC/DC converters in the 20 to 300kW power range, has been introduced by Semikron. The Semitrans modules are available with Fuji fifth-generation V-IGBT chips as an alternative to IGBT4 chips. The very low 15nH module inductance offers two advantages: 50V higher DC link voltage than in competitor modules, due to the lower switching over-voltages; plus faster and softer IGBT switching producing lower switching losses, boosting overall efficiency In addition to the existing Semitrans modules with IGBT chips from Infineon, Semitrans modules now also are available with V-IGBT’s from Fuji, offering a blocking voltage of 1200V. The new V-IGBT based modules are available in three different sizes, a total of eight different power classes and three switching topologies, with rated currents of 150A to 600A. Semitrans 3 and 4 modules are very low-inductance modules with a module inductance of just 15nH. The typical IGBT switching speed of 5000A/µs results in a module overvoltage of just 75V. Competitor products produce on average module over-voltages of between 90V and 125V. The modules come in single-switch, half-bridge or chopper topology for inverters in industrial drives or any other application area.
