SEMIKRON introduces its newest low-inductance 1200V SEMITRANS IGBT module series for use in AC/DC converters in the 20-300kW power range. These modules are now available with V-IGBT chips as an alternative to IGBT4 chips. The very low, 15nH inductance boasts two advantages: 50V higher DC link voltage than in competitor modules, thanks to the lower switching over-voltages. Plus, faster and softer IGBT switching produces less 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 with a 1200V blocking voltage. The new V-IGBT comes in three different module sizes, a total of eight different power classes and three switching topologies. The modules are available with a rated current 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. By way of comparison, competitor products produce on average module overvoltages of between 90V and 125V. The modules come in single-switch, half-bridge or chopper topology specifically for inverters in industrial drives or any other given area of application.
Standard SEMITRANS modules boast high insulation strength of 4000V/min, which is 60% higher than the global insulation strength norm of 2500V/Min and serves to underline the superior quality of SEMITRANS modules.  In addition to the 1200V modules featuring IGBT2, IGBT2 fast, IGBT3 or IGBT4 technology, the modules are also available with a blocking voltage of 600V and 1700V.
Three standard SEMITRANS case sizes, 34-mm-wide SEMITRANS 2 and 62-mm-wide SEMITRANS 3 and 4 modules are available. Additional sizes for non-standard customer applications are also offered, for example SEMITRANS 6 with 6-pulse inverter bridge circuits, SEMITRANS 5 with circuits for 3-level inverters as well as for current monitoring, which is achieved by integrating shunts into the modules. SEMITRANS 9 was developed to provide a particularly high insulation strength of 9kV for railway applications. SEMITRANS modules all feature a copper baseplate.
