RF battery charger
This type of charger couples the RF voltage from L2 to an external electromotive force induction coil. The induction coil is connected to the rectifier and the battery being charged. This working principle is very convenient. Because it does not require wires or contacts, L2 uses 10T 24 wires or contacts. L3 is wound with 10T36 wire. Both coils are mounted on a 1 inch 1/4 inch ferrite rod.
