Traction, industrial equipment, building facilities, electric vehicles, renewable energies, home appliances... Power devices are a key component in power electronics products for contributing to the realization of a lowcarbon society. Attracting attention as the most energyefficient power device is one made using new material, siliconcarbide (SiC). The material characteristics of SiC have led to a dramatic reduction in power loss and significant energy savings for power electronics devices. Mitsubishi Electric began the development of elemental SiC technologies in the early 1990s and has since introduced them to achieve practical energysaving effects for products manufactured using SiC. Innovative SiC power modules are contributing to the realization of a lowcarbon society and more affluent lifestyles.
