Power Electronics for Solar Inverters
SEMIKRON’s portfolio includes a wide range of products for efficient solar inverters in all power ranges: residential, industrial and utility scale applications. From individual modules including dedicated drivers to high power SKiiP 4 IPMs and ready-to-use power electronic stacks – SEMIKRON has the solution.
SEMIKRON offers a large portfolio of 3-level modules, IPMs and power electronic stacks which can reduce system costs significantly as well as optimize annual energy production, especially for increased DC voltages of up to 1500VDC.
The Latest IGBT Generation from Two Suppliers for Highest Supply Chain Safety
SEMIKRON has introduced 950V and 1200V Generation 7 IGBTs from two different manufacturers. Both Generation 7 IGBTs have fundamental improvements over the previous versions. Thanks to a new chip design, the chip size is an average of 25 % smaller across all current classes. This technology allows higher current density and an approximately 20% reduction in saturation voltage Vce,sat.
This new chip generation allows for compact inverters with unprecedented power density. Especially the new 950V IGBTs, in avariant for high switching frequencies as well as a variant with optimized Vce,sat, are ideally suited for use in 3-level topologies up to 1500VDC.
Additionally the Generation 7 IGBTs share the following features:
Generation 7 IGBT Power Modules
The Power Density Master: New Levels Utilizing the Latest Generation 7 IGBT Chips
For increased power density and high reliability, SEMIKRON now utilizes 950V IGBTs in the MiniSKiiPs. With this Generation 7 IGBT chip, both boosters and 3-level topologies have been optimized for the 1500VDC market. Along with the existing portfolio, the MiniSKiiP provides a power dense design for the string inverter market up to a power range of 300kW without paralleling of modules.

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.

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
