Company information
The richness of our lives is supported by the use of electrical energy. As a result of the massive consumption of this electrical energy, we are facing environmental and energy issues. The key lies in the spread of energy-saving and new energy products. These are technologies that handle energy more efficiently and generate cleaner electrical energy. We aim to leverage the power conversion technologies (power electronics) we have developed so far to contribute to the realization of a low-carbon society, which is a common challenge for humanity, through the "electrification of vehicles."
