Increased Performance in 3-Level Topologies

In order to achieve economy of scale, manufacturers typically use the same hardware for solar and energy storage converters. While the three-level NPC topology works well for solar, this can often mean de-rating for energy storage while in charging mode. Thanks to the chip shrinkage from Generation 4 to Generation 7 IGBTS, there is more space for diodes. Therefore, the SEMITRANS 10 MLI offers an increased clamping diode current rating. This enables energy storage converters to work at full power while charging and discharging batteries.

The Latest Generation 7 IGBTs for Highest Supply Chain Safety

Whenever power quality and efficiency are driving factors in power electronics applications, 3-level topologies are the key. This is especially true for renewable energy applications where the combination with the latest Generation 7 IGBTs sets new benchmarks.

For ANPC topologies, our new SEMITRANS 20 power module combines low stray inductance, high power density and Generation 7 IGBTs to set a new benchmark. This package design, based on standard half-bridge topology, allows a simple ANPC layout with low inductance DC-link connections.

Intelligent Power Modules - IPMs

For Maximum Reliability for Solar and Energy Storage Converters

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 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 a 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 parameters and reading application parameters.

High Perfomance 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 interface. 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.
