Safe and reliable power electronic systems for vehicle applications SEMIKRON and hofer pool their ex

SEMIKRON and hofer powertrain are developing a flexible inverter system for using in mass production in field of hybrid and electric vehicles. The new Semikron SKAI 2 IGBT system was presented in May this year which is now available as custom specific solution including control hardware, software and also safety functions from hofer. The portfolio covers a power range of 600V IGBTs for applications up to 150kVA and 1200V IGBTs for up to 230kVA.

The custom-specific SKAI systems fulfil current requirements and qualification standards as regards EMC, vibration, IP protection class, safety functions and lifetime in automotive industry. The verified safety functions enable the use of both asynchronous and synchronous motors and guarantee reliable operation. SKAI modules are also suitable for multi-electrical drive systems.

The platform solution is the most suitable way for test vehicles and a low-volume production. Furthermore hofer also develops and supplies entire electric powertrain systems including motor, transmission and full electric axle modules for hybrid and electric vehicles.

hofer electric drive systems is the specialist in electric drive systems and offers an extensive spectrum of products and services ranging from the necessary software to application-specific know-how and support. The company has many years of experience in development and application in the field of electric drive systems. hofer eds team was responsible for the electric drive systems used in hybrid and electric vehicles for Siemens VDO. They also developed and tested a full hybrid as well as a mild hybrid to series-production level.

SEMIKRON’s SKAI2 product platform is predestined for use in automotive applications owing to the use of pressure contact technology. The experience that Semikron has gained in the area of battery powered vehicles over two decades has been integrated in the SKAI product family. Users benefit from this long-time experience is the availability of the SKAI platform as a standard solution.
