Addressing EMI Issues Plaguing Wireless Power Transfer (Download)
Electromagnetic fields (EMFs) are made up of both electric fields and magnetic fields. Electromagnetic interference (EMI) is caused by the interaction of EMF in applications like wireless power transfer (WPT) systems.
Wireless power transfer is used to charge everything from smartphones to smart watches. WPT standards have been around for a while and the latest technology has improved power efficiency and high power levels. The Wireless Power Consortium’s Qi standard utilizes inductive charging.
