- Abstract
- In this paper, the PCB layout changed to reduce the electromagnetic interference noise from switch mode power supply in the wireless power transmission system. The critical current loop minimized to reduce the radiated noise. The noise was reduced by a maximum of 18 dB compared to the previous.
