Disclosed is a wireless charging power supply system during operation of electric vehicles and industrial equipment while operating. The withstand voltage problem on the power supply line was solved by the capacitor provided in the inverter, and the power supply line and common line arrangement. This makes it possible to extend the wireless power supply line and the economical problem of the wireless charging system is greatly improved.In the prior art, compatibility was maintained with various wireless charging pick-up pads installed in the vehicle by using a plurality of inverters. In this system, compatibility is satisfied at a lower cost by utilizing the relay present in the inverter. The EMI of the power supply line is reduced by maximizing the magnetic field cancellation effect by using the structure of the common line and the shielding tube.
