Introduction Application hints How to start P primary side pinning Setting parameters Active clamping Circuit diagram... 7 Please consider the technical explanation of SKYPER 12 R L as all electrical functions are described in there. 1. Introduction The Board SEMIX5 MLI SKYPER 12 R is an adapter board which can be used for driving the MLI module SEMIX5. The board can be directly plugged on the module. Figure 1: Board SEMIX5 MLI SKYPER 12 R Fits to 600V, 1200V & 1700V modules Drives MLI IGBT modules I outave C Safe short circuit handling with SoftOff and active clamping Important: Please make sure to consider the three level error management application note when switching MLI modules. by SEMIKRON / / Technical Explanation / TechEx Board SEMIX5MLI SKYPER 12 Page 1/10

2 2. Application hints Gate resistors The gate resistors can be assembled via SMD process. Gate resistors values should be chosen as low as possible to have low switching losses. But over voltages over the full temperature range during standard switch off and during short circuit switch off are the limiting factor and must be checked. Active Clamping/ SoftOff The active clamping has to be set according to the required DC link voltage and has to be proven during short circuit conditions.
