Induction coil for phone charger

Hezhi Hardware (Vietnam) Technology Development Co., Ltd. specializes in producing all kinds of transformer coils, widely quoted in mobile phone chargers, , wireless charging and so on.

The electronic transformer has an electronic device that converts the alternating voltage of the commercial power into a direct current and then forms a high-frequency alternating current voltage output through the semiconductor switching device and the electronic component and the high-frequency transformer winding, and is also described in the electronic theory. A crossover inverter circuit. Simply put, it is mainly composed of a high-frequency transformer core (core) and two or more coils, which do not change position from each other, from one or two electric circuits, through AC power Magnetic induction, converted into AC voltage and current. At the output of the high-frequency transformer, one or two or more power circuits are supplied with high-frequency alternating current or direct current of different voltage levels.

Electronic transformer coil:

1. Material: three layers of insulated wire

The triple insulated wire is a high-performance insulated wire. The wire has three insulating layers with a core wire in the middle. The first layer is a golden yellow polyamine film with a thickness of several micrometers, but can withstand a pulse high voltage of 3KV. The second layer is a highly insulating spray paint coating, and the third layer is a transparent glass fiber layer. The total thickness of the insulating layer is only 20-100 um, which has the advantages of high dielectric strength and can withstand communication between any two layers. 3000V safe voltage, high current density.
