The effective use of electrical energy is a key technique for achieving energy efficiency, and power electronics technologies that can convert electric power into the optimum characteristics for each applications are essential part of this approach. Power electronics systems have attracted attention as key components for building a sustainable society by reducing CO2 emissions and include the use of inverters as adjustable-speed drives for motors and PCSs that provide stable connections to the power grid for unstable DC or AC electric power generated from solar energy, wind energy, etc. Hitachi provides systems, products, and services that contribute to reducing CO 2 emissions in power generation, industry, and other sectors in social infrastructure by combining power electronics with system control technologies and technologies for power devices which are the key components in these systems.
