Power Electronics for Traction Applications
Whenever we talk about traction applications, we see extremely high demand for reliability, lifetime and safety. SEMIKRON is offering this requirements to our customers since we developed the first isolated power module on the market in 1974. Since 25 years our highly reliable SKiiP IPMs are driving light rails, trams and subways all over the world.
With our new SEMITRANS 20 power module familiy, SEMIKRON brings latest sinter and bonding technology to the new high power standard package. SEMIKRON stands also for innovative solutions for auxiliary power supplies: our silicon and silicon carbide powered devices, especially the SEMITRANS and SEMITOP module families, allow reliable, efficient and compact systems.
The New High Power Standard in Traction Drives
The SEMITRANS 20 product family increases product lifetime- and power output. SEMITRANS 20 modules deliver significant advantages for the traction market:
On top of this, the SEMITRANS 20 TRACTION module provides SEMIKRON innovative technologies such as sintered chips and AlCu wire bonds. This takes realiability and power density to new levels, resulting in:
- Standard package for traction and industrial applications
- Innovative technologies with sintered chips and AlCu wire bonds
- Next level lifetime and power density
- Lower mounting and material cost in inverter assemblies
- Ideal for paralleling and scaling

Intelligent Power Modules – IPMs
For Maximum Reliability
The SKiiP IPM product line sets a benchmark for high performance and robust inverter designs. Both SKiiP 3 and SKiiP 4 feature high power densities combined with flexible cooling options such as air-or water-cooling, also with customized heat sinks. Reliable driver technology, integrated current sensors and comprehensive protection functions complete the IPM design.
SKiiP 3 has propagated widely through the industrial drive segment. With its sixpack or half-bridge topologies, it covers a current range from 500A up to 2400A.
The SKiiP 4, available in half-bridge topology, has been optimized for highest power cycling requirements and covers the higher power range up to 3600A.
To ensure highest reliability and service life, the power circuitry is 100% solder-free. Sinter technology as die attach replaces the solder layer, which usually causes the limitation in lifetime. Hence, sintering improves power and thermal cycling capability.
The integrated gate driver in the SKiiP 4 has set new standards in terms of reliability and enhanced functionality through its CAN interface. The digital driver guarantees safe isolation between the primary and secondary side for both switching signals and parameter measurement. The CAN interface allows setting the SKiiP 4 configuration parameter and reading application parameter.
High performance cooling technology will be gradually introduced providing approximately 20% more output capability compared to standard water cooling.
- 1200V and 1700V
- Half-bridge and sixpack
- 500A to 3600A
- Flexible cooling options: air, water or customized cooling options, high performance cooling
- Paralleled operation for even higher output power possible
- Special version for 1500VDC available
Product Portfolio IGBT Driver
Above the Standard
SEMIKRON’s unique product portfolio enables access to all esta-blished industries with a one-stop solution that combines state-of-the-art power modules and driver electronics.
SEMIKRON’s IGBT drivers are available as two- channel driver cores suitable for any standard semiconductor power module or as Plug-and-Play solutions, which perfectly fit the SEMiX 3 Press-Fit, SEMITRANS 10 and compatible modules.
Achieve outstanding system compactness and create space-and cost-effective inverter designs with SEMIKRON’s drivers, utilizing highly integrated ASIC technology. Isolated DC-link voltage and temperature sensor signals at the driver’s interface along with over-voltage and over-temperature lockout also help to reduce system costs significantly.
More than 25 years of experience in developing innovative IGBT driver electronics enables SEMIKRON to have a short-term solution for almost every challenge related to driver electronics. SEMIKRON’s Plug-and-Play drivers connect directly to most common standard IGBT modules. The IGBT driver cores fit with SEMIKRON’s adapter boards or application sample PCBs. For the latter, SEMIKRON shares the entire manufacturing data to decrease development time, speeding up the time-to-market.
SEMIKRON’s SKYPER and SKHI IGBT drivers are well known, highly robust and reliable IGBT driver solutions under demanding environmental conditions. Over many years of field operation experience the proprietary IGBT driver technology has been relentlessly developed further. This technology sets new standards for the essential features of safe gate control, reliable gate protection and reinforced insulation.
- Reinforced insulation for signal and power transmission
- Two-channel driver
- Up to 1700V transients
- Up to 1500V continuous DC bus voltage
- 8Apk to 35Apk per channel
- 1W to 4.2W peak per channel
- Suitable for multi-level topologies and Generation 7 IGBT
Thermal Interface Materials
Stay Cool – Heat Dissipation is Our Job
SEMIKRON was the first power module manufacturer on the market to offer power modules with pre-applied thermal interface material. With more than two decades of field experience and more than 15 million pre-printed modules in the field, benchmarks are being set. The modules with pre-applied TIM are printed in a clean environment on an automated and SPC controlled silk screen and stencil printing line.
For each requirement SEMIKRON offers the right choice of material. In addition to the standard silicone thermal grease, phase change materials and high performance thermal paste with improved thermal performance are also available.
SEMIKRON offers either thermal grease or phase change mate- rials depending on customer requirements (e.g. performance increase, reduced handling effort) and module type (with or without baseplate). Phase change materials have a solid consistency at room temperature, fully exploiting the advantages a non-smearing TIM layer offers, with no drawbacks. Baseplate- less modules, on the other hand, usually require a lower-viscosity material to help improve robustness during assembly. Here, thermal grease is the preferred solution.
- Increased productivity thanks to reduced handling costs and improved logistics
- Low thermal resistance with optimised TIM layer thickness
- Improved lifetime and reliability
- Improved assembly robustness
- Modules can be shipped directly to the assembly line without any additional treatment processes
- Lower overall costs
