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 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 8kW up to the megawatt range.

Product Highlights
Industrial Standard Combined with Superior Performance
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 in a wide array of topologies.
Key Features
- Low inductance package
- Multiple sourcing down to chip level
- Optimized footprint
- Flexible architecture
- 2-screw concept
- Press-Fit terminals
- 12mm module height
- No baseplate
The thermal resistance is up 20% lower than the closest competitor using standard thermal paste. Using High Performance Thermal Paste (HPTP), a further 25% reduction is possible.

Thermal Interface Materials (TIM)
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 in thermal paste form. 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.
Key Features
- 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
Portfolio
- P8: Phase Change Material for highest performance
- HT: Phase Change Material for highest sink temperature
- HPTP: High Performance Thermal Paste
- P12: Standard Thermal Paste
