MISSIONHeadspring’s technologies

To popularize smart energy equipment (solar power generation, wind power generation, electricity storage systems, electric vehicles, etc.), which is expected to grow rapidly, we commercialized general-purpose power converters using next-generation power semiconductors (SiC, GaN) for better conversion efficiency, more compact designs, and lower prices. We will create more market opportunities through globalization and horizontal specialization within the industry to popularize the smart energy equipment required by each country.

About power electronics

What is power electronics?

Power electronics technology is referred to as semiconductor power conversion technology, which is a technology commonly applied to systems centered on power conversion and control using power semiconductor devices.
Power electronics can transform DC voltage (to a higher voltage or lower voltage) or converts DC to AC (inverter) through fast ON/OFF switching via power semiconductors.
The technology can be used in a very wide range of areas: the electrical power sector for power generation and power distribution; industrial equipment such as motors and pumps; power supply units for communication systems, factories, and other facilities; the electrical railroad sector for train drive units and power transformation; automobiles; and electronic household products. A large number of sectors can conserve energy via the utilization of power electronics technologies. Recent demand for greater energy conservation and lower carbon emissions has led to growing expectations for the potential of power electronics technologies.

Technologies required for power electronics

Power electronics technology is often described as a technological area where power, electronics, and control are unified.
Diverse technologies involved in power circuits, analog circuits, digital circuits, electric power engineering, electromagnetics, control engineering, microcomputer technology, and information and telecommunications technology are required for the development of power electronics products. In other words, the objective of power electronics technology is to pursue greater conservation of electrical power and energy by reducing power conversion loss in the use of those technologies.

Technologies required for power electronics

Power semiconductors generally refer to semiconductor devices that control electrical power and power supplies. They are used in a variety of equipment and components that include home appliances, computers, automobiles, and railroads. Conventional power semiconductors have used Si (silicon), though attention is currently focused on next-generation power semiconductors that utilize SiC (silicon carbide) and GaN (gallium nitride) instead. SiC-based semiconductors are starting to be used in power electronics (inverters) of high-voltage type for railroads, household appliances, and industrial equipment, while GaN, with its excellent high-frequency properties, is expected for use in power supply units for communications equipment.
