Summary:
The electromagnetic interference (EMI) from the coil system for the wireless power transfer (WPT) with the voltage source and series LC resonance type can be reduced by 20dB at the most by using the spread spectrum technology when operating frequency 20 kHz, peak deviation 1%, and modulation frequency 156.25Hz.
