Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end.
Wireless charging methods include electromagnetic induction,Magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. As shown below.
Mobile phone wireless charging is a relatively novel charging method, the principle is actually very simple, is to separate the ordinary transformer primary and secondary levels to achieve the purpose of wireless. Of course, the working level of wireless charging is relatively high, and even the core direct coil can be abandonedThe demographic dividend has ended, and foreign-funded enterprises in Dongguan can not get any profits, so they withdraw. A wholly foreign-owned enterprise, referred to as a foreign-funded enterprise, refers to an enterprise established within the territory of China in accordance with the laws of the People's Republic of China with all its capital invested by foreign investors. 2, it is understood that Dongguan will strive to promote the reform to all foreign-funded enterprises in the fourth quarter of this year, and expand to all domestic enterprises next year, to further achieve the facilitation of the city's enterprise license processing.
3. Dongguan Government gives strong support to foreign-funded enterprises at the policy level. By July 25, 2023 through the inquiry of Dongguan government website letterIt shows that so many foreign companies in Dongguan Changan are the Dongguan government's strong support for foreign-funded enterprises at the policy level, and Dongguan's "Ten foreign investment" and other supporting policies have provided broad development for foreign-funded enterprises.

Sichuan transformer manufacturers include Nanchong Wanxingyu Technology Co., LTDCompany, Sichuan Fumeigao Electronics Co., LTD., Sichuan Feiqi Electric Co., LTD., Sichuan Shubian Electrical Equipment Co., LTD. These manufacturers produce and sell different types of transformers, such as high-frequency transformers, inductors, current transformers, switching power transformers, etc., which are widely used in power, electronics, communications and other fields.
Domestic inductor leading enterprises are mainly Shun Luo, Maijie, Kedajia, Fenghua High-tech and other enterprises, but each product line and applicationThe scenes are all different. For example, Kedaja Electronics mainly produces large-size inductors for the industrial and automotive markets, and Kedaja leads in flat line high-current inductors; Shunluo, Maijiewei, Fenghua High-tech and other enterprises are mainly for the consumer market to do small chip/laminated inductors.
Shenzhen Jingye Magnetic Electronics Co., LTD. / Youtuo Electronics (Guangzhou) Co., LTD. / Dongguan Mingpu Industrial Co., LTD. / Yiyang New Era Powder Metallurgy Co., LTD. These are quite large. You can go to the big bit electronic transformer website to see above, there are information and contact information about inductor manufacturers, as well as supply and demand letters in this areaBreath.
