SEMIKRON presents the first IGBT driver for direct press-fit mounting

SKYPER 12 press-fit for 17 mm modules with new generation of ASICs

(PresseBox) ( Nuremberg, )
Easy assembly, electrical robustness and a long service life: The new SKYPER 12 press-fit half-bridge driver was developed with these aspects in mind. It is pressed directly onto the IGBT module, which means that there are no costs for an adapter board, cable splices, and associated assembly and soldering processes.

With 30% fewer components than available plug&play solutions, the driver reduces the failure rate of the individual components and achieves an MTBF (mean time between failures as per SN 29500) rate of over 5 million hours at full load. This means that safe IGBT control is ensured even for the long working lives of industrial drives.

A new generation of mixed-signal ASICs achieves a high level of integration. The ASIC chip set contains the power supply and protection and control functions, and the external components ensure optimum thermal spreading. The costs are reduced and the lower risk of failure increases reliability. Thanks to short pulse suppression and an interface ground concept, the usual good EMC stability of the SKYPER family is achieved. With square-wave signal transmission, the SKYPER 12 even switches without errors at a high dU/dt. The mixed-signal ASICs work in a stable manner over the entire temperature range with no transit time differences.

The SKYPER 12 sits on 17 mm press-fit modules without an overhang and safely controls the modules up to a 15 A peak current and a DC link voltage of up to 1,200 V. The soft turn-off function and VCE monitoring feature protect against overvoltages in the case of a short circuit. Integrated temperature monitoring serves to avoid overload, so the external isolation of the temperature signal is not required. The ASICs developed by SEMIKRON thus monitor customer-side and internal voltage supplies. Thanks to adequately dimensioned buffer capacitors - the driver switches the IGBTs off safely in every kind of faults.
