Abstract

The invention discloses a mobile phone wireless charging circuit. The mobile phone wireless charging circuit mainly comprises a wireless transmitting module and a receiving module; the wireless transmitting module comprises a voltage transformation circuit, a rectifying voltage-stabilizing circuit, a high frequency inversion circuit and a detection circuit; and the receiving module comprises a rectifying voltage-stabilizing circuit and a charging management circuit. The high frequency inversion circuit and the detection circuit of the transmitting module are operating around the efficiency peak, and the circuit safety is greatly ensured; the output voltage of the rectifying voltage-stabilizing circuit of the receiving module is adjustable, and a charging management chip can be operated in the best state; and therefore, safe and rapid mobile phone charge can be realized by appropriately selecting the charging management chip. The mobile phone wireless charging circuit has the characteristics of convenient use, high reliability, safety, stability and the like.

Description

technical field [0001] The invention belongs to the technical field of wireless charging and relates to a circuit, in particular to a wireless charging circuit for a mobile phone. Background technique [0002] With the increasing screen size of smartphones, more functions, more power consumption, and more frequent charging of mobile phones, messy data lines and frequent plugging and unplugging make people feel annoyed about the charging process , so people need a more reliable and convenient charging method. Mobile phone wireless charging technology is a technology that relies on spatial magnetic field coupling to transfer the power from the power supply end to the mobile phone battery to charge it, which overcomes the disadvantages of traditional mobile phone charging. Although this technology has attracted the attention of relevant institutions and enterprises and some related products have been launched on the market, the existing wireless charging products have defects ...
