Wireless Power Supply Inverter Products
In 2008, SPC Electronics commercialized wireless power supply inverters and has since participated in demonstration tests for dynamic wireless charging of electric vehicles. Through these initiatives, we contribute to the development of wireless power supply systems as next-generation infrastructure for automobiles, railways, and personal mobility solutions.
