Analysis And Design Of Wireless Power Transfer System (Wireless Power Transfer)

open access: yesJurnal Mekintek : Jurnal Mekanikal, Energi, Industri, Dan Teknologi, 2020
Wireless Power Transfer is a way of sending electrical energy through air media, so that electrical energy can be transmitted from a power source to an electrical load without using a conductor or cable. The maximum distance that can be sent by the transmitter to the receiver is 5cm with a voltage of 1.3 volts. This proves that the farther the distance
