Power Electronics for Motor Drives
Since the first appearance of motor drives, SEMIKRON has been committed to supplying solutions for every power range. Starting with the first insulated power module, the SEMIPACK rectifier module series more than 40 years ago, the MiniSKiiP in particular has revolutionised the motor drive design for low and medium power systems.
Today SEMIKRON offers the complete industrial standard power module portfolio that serves a power range of 0.2kW to several megawatts. The portfolio is completed with high power IPMs, power electronic stacks and a comprehensive product line of driver electronics that help to reduce development effort and time-to-market. The latest Generation 7 IGBTs of two different suppliers, optimized for motor drive applications, boost performance and power density.
The Latest IGBT Generation from Two Suppliers for Highest Supply Chain Safety
The Generation 7 IGBT chips T7 and M7 enable higher power density and higher performance. Thanks to a new IGBT cell design technology the chip size could be reduced by approximately 25% compared to the previous generation.
The features translate into up to 20% higher output power in given power package sizes and motor drive applications. Thanks to the higher allowed operation temperature an overload of e.g. 110% can be covered without the need of additional design reserves.
Additionally the Generation 7 IGBTs share the following features:
The Power Density Master: New Levels Utilizing the Latest Generation 7 IGBT Chips
One continuous mounting concept from 0.4 to 110kW
One continuous module concept for all voltages and topologies
First SEMIKRON module to provide Generation 7 IGBT
IGBT and Rectifier Module Family for Complete Motor Drive Solutions
SEMiX 3 Press-Fit features IGBT and rectifier modules in the same housing design for a complete medium/high power drive solution. As an industry standard power module available with the latest generation IGBT chips from different suppliers, it gives a full supply chain safety.
It‘s your choice: SEMiX 3 Press-Fit is available with optional ...
... integrated current measurement shunts. The integration of the current measurement into the power module replaces expensive and bulky current sensors (i.e. Hall sensors) . This reduces size and cost of the motor drive system
... Plug-and-Play driver SKYPER 12 Press-Fit. Simply pressed onto the power module‘s press-fit pins, the driver reduces time-to-market thanks to a ready-to-go solution
... pre-applied phase change material (PCM). The choice between two different materials optimises either the thermal performance or the allowed heatsink temperature.

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 and water cooling, also with customized heatsinks. 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 (HPC) technology has been introduced providing approximately 25% more output capability compared to standard water cooling. A double side mounting HPC water cooler is also available and enables an even higher power density.
- 1200V and 1700V
- Half-bridge and sixpack
- 500A to 3600A
- Flexible cooling options: air, water or customized cooling options, high performance cooling, single and double side mounting water coolers
- Paralleled operation for even higher output power possible

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 17 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 silkscreen 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 materials 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 optimized 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
