Development of Mitsubishi Electric SiC Power Devices
and Power Electronics Equipment Incorporating Them

Mitsubishi Electric began developing SiC as a new material in the early 1990s. Pursuing special characteristics,
we succeeded in developing various elemental technologies.
In 2010, we commercialized the first air conditioner in the world equipped with a SiC power device.
Furthermore, substantial energy-saving effects have been achieved for traction and FA machinery.
We will continue to provide competitive SiC power modules with advanced development and achievements from now on.

R&D SiC Power Devices

SiC with superior characteristics

SiC with superior characteristics

Power loss reduced

SiC has approximately 10 times the critical breakdown strength of silicon. Furthermore, the drift layer that is a main cause of electrical resistance is one-tenth of the thickness. This allows a large reduction in electrical resistance and, in turn, reduces power loss. This SiC characteristic enables dramatic reductions in conductivity loss and switching loss in power devices.

SiC with superior characteristics

High-temperature operation

When the temperature increases, electrons are exited to the conduction band and the leakage current increases.
At times, this results in abnormal operation.
However, SiC has three times the band gap width of silicon, preventing the flow of leakage current and enabling operation at high temperatures.

SiC with superior characteristics

High-speed switching operation

With SiC, owing to the high dielectric breakdown, power loss is reduced and high-voltage is easier to achieve, it is possible to use Schottky Barrier Diodes (SBDs), which cannot be used with Si. SBDs can realize high-speed switching motion because they don't have accumulation carriers. As a result, high-speed switching can be realized.

SiC with superior characteristics

Heat dissipation

SiC has three times the heat conductivity of silicon, which improves heat dissipation.
