Abstract

The invention discloses a wireless charging circuit, comprising a first S resonance compensation circuit arranged on the primary side, a second S resonance compensation circuit and an LCL resonance compensation circuit arranged on the secondary side, the first S resonance compensation circuit includes a series arrangement The first resonance compensation capacitor and the first energy transmission line; the second S resonance compensation circuit includes a second resonance compensation capacitor and a second energy transmission coil arranged in series, and the LCL resonance compensation circuit includes a third energy transmission coil and an inductor arranged in series, Both ends of the third energy transmission coil are connected in parallel with a third resonant compensation capacitor, and the output ends of the second S resonant compensation circuit and the LCL resonant compensation circuit are respectively connected with rectification circuits. The invention also provides a parameter selection method for a wireless charging circuit to realize constant power wireless charging. The invention directly supplies power to electric equipment running at constant power without using batteries, thereby saving costs.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charging circuit and a parameter selection method for realizing constant power wireless charging. Background technique [0002] In recent years, wireless charging technology has attracted widespread attention from all walks of life and has developed rapidly due to its safety, reliability, convenience, and no plugging and mechanical wear during use, which can effectively improve the service life of equipment. [0003] At present, the output of most wireless charging systems is constant current or constant voltage, which is only suitable for charging the battery first, and then the battery supplies power to the electrical equipment. When the power of electrical equipment is large, more batteries are needed, which will greatly increase the cost; at the same time, the use of battery-powered indirect power supply is not suitable for some equipment with constant po...
