Significant energy-saving effect of SiC power devices. Energy consumption saved is equivalent to the power of 7 to 8 nuclear power plants.
As known, the power devices are currently used in a variety of fields, including air conditioners, automobiles and power plants. If the current power devices, which are used in Japan, are all replaced with SiC power devices, the energy consumption saved is equivalent to the power of 7 to 8 nuclear power plants (This is shown by the calculation). The SiC power devices were incorporated into the inverters of the railway vehicle being under test, by Mitsubishi Electric last autumn, and are called next generation power devices. The SiC power device can withstand much higher voltage and much larger current when compared with conventional silicon type power device, and suffers from significantly much less power loss than of the conventional power device.
