That Support Society
What does "freely transforming electricity" mean?
The electricity generated by power plants and other facilities cannot be used as it is. It must be transformed.
There are roughly four different ways of transforming electricity.
1 | Converting direct current | 2 | Converting alternating current |
electricity to alternating current. | electricity to direct current. | ||
3 | Changing the frequency of | 4 | Changing the voltage of direct |
alternative current electricity. | current or alternating current |
What does "efficiently converting electricity" mean?
There is always a loss of electricity every time a power conversion occurs in the process from power generation at a power plant, through transmission lines and power supply circuits to the final operation of electric appliances by consumers.
Power semiconductors
Are devices that strictly control the electric current flow and the voltage level, including transformation from an alternating current into a direct

The Sansha Electric Manufacturing Group uses technologies based on the methods for these conversions to transform and control electricity in the manner that is best suited to the purpose of use of the power supply to support society in many different areas.
To reduce this power loss, we are working to develop high performance power devices and high efficiency power supplies.
