Performance Range

Since the first appearance of motor drives, Semikron Danfoss has been committed to supplying solutions for every power range. Almost 50 years ago, Semikron Danfoss introduced the first insulated power module: the SEMIPACK rectifier. Since then, other innovations for motor drives have been introduced, with the MiniSKiiP in particular revolutionizing the design of low and medium power systems.

Today, Semikron Danfoss offers the complete industry standard power module portfolio that serves a power range of 0.2kW to several megawatts.

With the latest generation of IGBTs and SiC MOSFETs from multiple suppliers, our power modules boost performance, power density, and effiency in motor drive applications.

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.

Technology Highlights

Silicon Carbide MOSFETs for New Degrees of Freedom in Design

Compared to the latest generation Si IGBTS, the switching and conduction losses of SiC MOSFETs are considerably lower, thus offering designers new options for efficient drive platforms.

Increased power density allows for more compact drives or more power from given thermal designs. Faster switching with lower losses enables silent motor operation and smaller magnetics. Additionally, with SiC users can exploit new energy saving potentials. On a system level, this leads to a fast return on investment and reduced total cost of ownership. It also represents an important step towards more efficient energy utilization and decarbonization of the industry. Power modules with silicon carbide MOSFETs allow designers to push boundaries and re-think drives design.

With decades of experience in packaging power modules and supply chain reliabilty secured by strong, long-term partnerships with all top chip manufacturers, Semikron Danfoss is your ultimate partner for silicon carbide.

RGA IGBT for True Multiple Sourcing

With the ROHM RGA IGBT, a newly designed 1200V, trench gate, light punch through IGBT, we introduce a powerful alternative to current Generation 7 IGBTs.

The RGA IGBT, which was developed with motor drives in mind, is widely compatible to latest Generation 7 IGBTs. Likewise, it can be continuously operated at Tj,max=150°C and intermittently at Tj,max=175°C. Gate voltages are identical and the gate charge is even lower, thus it can easily be driven by existing driver circuits.

The RGA also offers advantages when comparing it to market available Generation 7 IGBTs. The chip size is optimized so that the thermal resistance is lower and a power module with RGA IGBT runs cooler. This allows for an increase of power or a reduction in cooling. Additionally, while typical Generation 7 IGBTs desaturate at twofold nominal current, the RGA IGBT can handle threefold nominal current, thus offering higher peak current tolerance.

With the ROHM RGA IGBT packed into our MiniSKiiP and SEMITOP E industry standard housings, there is now a true alternative to Generation 7 IGBT power modules.

Product Highlights

Full Scalability for PCB-Based Designs

With two decades of field experience and more than 60 million modules in the field, the MiniSKiiP platform has proven successful in all standard applications.

The unique mechanical design offers the simplest possible assembly. Heatsink, module and PCB connected with one or two screws in a single step, making solder or press-in processes and tools obsolete. In terms of sensivity to mechanical or thermal stress, the springs doing the electrical connection between PCB and power module have proven to be far superior to solder or press-fit joints.

With its wide power range, the MiniSKiiP product family provides a unique base for scalable PCB-based drive designs from 0.4kW up to 110kW. With a variety of topologies, it is the perfect match from single-axis drives to single PCB assemblies with multple axes.

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.

Semikron Danfoss Image Thermal Interface Materials

Thermal Interface Materials

Stay Cool – Heat Dissipation is Our Job

 

Semikron Danfoss was the first power module manufacturer on the market to offer power modules with pre-applied thermal interface material (TIM). We now have over two decades of experience and more than 25 million pre-printed modules in the field.

We design print patterns for each module type for the best TIM distribution and thickness when the module is mounted to a heatsink. These patterns are printed on the modules in a clean environment on an automated silkscreen and stencil printing line. Statistical process control (SPC) is used to guarantee consistency. Special packaging is implemented to ensure that the TIM arrives at your production line in pristine condition.

In order to achieve the best thermal performance in all applications, Semikron Danfoss power modules can be supplied with our High Performance Thermal Paste (HPTP).

Alternatively, for ease-of-handling during assembly, most power modules are also available with pre-applied phase change material (PCM). Phase change materials have a solid consistency at room temperature. With the application of heat during first operation, the PCM flows to fill gaps and provide a thermal in- terface. With HP-PCM, the new Semikron Danfoss-exclusive High Performance Phase Change Material, we combine the benefits of a phase change material with the performance of the best available paste.
