Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a mobile terminal wireless power supply system. Background technique [0002] In the field of communications, with the development of industrial production and science and technology (especially power electronics technology), electrical equipment is becoming more and more popular, and higher requirements are placed on the power supply methods of existing electronic equipment. Since the traditional power supply method basically adopts the transmission method of direct conduction of contact electric energy, and this method has problems such as poor mobility, unsafety, and especially not suitable for harsh environments (underwater, humidity, etc.), it can no longer meet social development. demand. Therefore, based on this problem, a technology that transmits electric energy in a non-electrical direct contact manner, that is, wireless power transfer technology (WPT), ...
