July 2018 – Semikron’s SiC Power Modules

Published on: 25/07/2018

Introducing Semikron’s SiC Power Modules available from 10kw to 350kw in 1200V

Semikron’s SiC Power Modules feature leading chip and packaging technology for the highest energy efficiency.  The Full/hybrid SiC modules range from 10kw up to 350kw in 1200V and are typically used in the following applications: solar inverters, energy storage systems and motor drives.

Both the hybrid and full silicon carbide power modules combine the benefits of proven industry standard power modules with SEMIKRON packaging technologies.

A low module commutation inductance allows for full speed switching of SiC MOSFETs. The higher switching speeds can be converted into higher switching frequencies, resulting in smaller magnetic filter components. The switching losses can be reduced at the same time, increasing the system efficiency. Sophisticated materials and packaging technologies minimises the thermal resistance of the chip to the heatsink which enables higher power densities.

Semikron’s Silicon Carbide power range comes in seven different packages, the MiniSKiiP and SEMITOP represent the low power range of up to 25kW and are both baseplate-less.

The MiniSKiiP comes with tried and tested SPRiNG technology as a full SiC 6-pack, with or without SiC Schottky free-wheeling diodes. The first and second generation SEMITOP modules help achieve maximum flexibility in combination with the industry standard package SEMITOP E1/E2.

SEMITRANS 3, SKiM63/93 and SEMiX 3 Press-Fit are all covered by Semikron’s medium and high-power range and are available in hybrid and full SiC topologies for up to 600A rated chip current.  Fast rectifier modules with Silicon Carbide Schottky diodes are also available in SEMIPACK and SEMITOP packages.

Semikron’s SiC power modules feature higher switching frequencies which allow for optimised and lower-cost filter components, Their reduced power losses boost efficiency and lower the system costs and size because of the compact cooling devices.

Semikron’s SiC Power Modules
