Mitsubishi Electric successfully developed 6.5kV full SiC power module
As early as 2013, Mitsubishi Electric has commercialized the use of 3.3kV full SiC power modules for rail vehicles. Since then, Mitsubishi Electric has been committed to promoting more energy-efficient SiC power modules to gradually replace the traditional Si power modules.
On January 31, Mitsubishi Electric Corporation announced that it has successfully developed a full SiC power module with a 6.5kV voltage rating. The module uses a single-chip construction and a new package to achieve the world's highest level in the same power module from 1.7kV to 6.5kV. Power density (calculated by the rated voltage and current of the power semiconductor). Mitsubishi Electric expects to use this module to help miniaturize and save power electronic equipment for rail transit and power systems with high voltage requirements.
6.5kV full SiC power module sample
Features
1. 6.5kV full SiC power module helps to reduce power and energy saving of power electronic equipment
Realized the same maximum voltage of 6.5kV as the Si IGBT power module;
Full SiC technology increases power density and efficiency, and can help reduce the size and power of high-voltage converters by increasing the switching frequency of the device.
2, single-chip structure and high heat dissipation, high heat resistance of the new package, the world's highest power density of high-voltage power modules
Integrate SiC-MOSFETs and diodes on a single power chip to significantly reduce chip area;
Small insulation package with high heat dissipation and high heat resistance is realized by an insulating substrate with high thermal conductivity and high heat resistance and high reliability chip bonding technology;
The world's highest power density (9.3kVA/cm3) is achieved in power modules rated at 1.7kV to 6.5kV.
Product packaging
The new all-SiC power module is available in an industry standard package (Mitsubishi Electric HV100) and is compatible with our HV100 series Si IGBT modules.
