Power Electronics for DC Fast Chargers

As electric vehicles become widespread, so must the infrastructure to charge them. One of the main requirements for the widespread use of electric vehicles is having an accessible EV charging infrastructure. Governments and industries worldwide are preparing to invest in charging infrastructures.

Availability and costs are the key to success in the fast growing EV Charger market. As the specialist in power electronics, we use state-of-the-art topologies featuring standard components, guaranteeing both excellent efficiency and availability. SEMIKRON offers a comprehensive portfolio of products that meet the needs of fast charge equipment from as little as 22kW up to 450kW.

Product Highlights


Industrial Standard Combined with Superior

DC Fast Chargers require a power dense PFC, DC/DC, and output rectifier, all available in the SEMITOP E1/E2 packages. With a low inductance design, fast switching Si and SiC chips may be used to their full potential. Achieve supply chain safety with this industrial standard module with a wide array of topologies.

Key Features

  • Low stray inductance case
  • Multiple sourcing right down to chip level
  • Optimised footprint
  • Flexible architecture
  • 2-screw concept
  • Press-Fit terminals
  • 12mm module height
  • No baseplate

The thermal resistance is about 10% lower than the closest competitor using standard thermal paste. Using High Performance Thermal Paste (HPTP), a further 20% reduction is possible.

Product Portfolio IGBT Driver

Above the Standard

SEMIKRON’s unique product portfolio enables access to all established 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.

Key Factors

  • 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.

Key Features

  • 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
