Sustainability Helping Customers Reduce Their Environmental Impact
Power Semiconductors
The Ryoyo Ryosan Group provides power semiconductors, devices which play a key role in helping to build a decarbonized world.
1. What Is a Power Semiconductor?
Power semiconductors are used in electric power conversion devices such as inverters (from DC to AC) and converters (from AC to DC), as well as in devices that require conversion of voltage, current, or frequency.
2. Main Uses
The main customers for our power semiconductors are manufacturers of railway vehicles and photovoltaic (PV) systems. Railway vehicles require resistance to large currents and high voltages, while PV systems need to minimize power loss during power generation and electrical conversion.
3. Power Semiconductors Contribute to Society
As a key component in the devices and other equipment that our customers make, our power semiconductors reduce energy loss during power conversion and generation, thereby improving energy efficiency. This is just one of the ways that we helps to reduce the environmental impact of equipment to promote energy conservation and decarbonization.
Other Initiatives
The Ryoyo Ryosan Group contributes to addressing social issues, such as reducing environmental impact, through our businesses related to next-generation energy and high-performance computing.
