Multi-transmitting multi-receiving magnetic-resonance wireless charging system for medium-power electronic apparatus

Abstract

A multi-transmitting multi-receiving magnetic-resonance wireless charging system for a medium-power electronic apparatus includes a magnetic-resonance transmitting module and a magnetic-resonance receiving module. The magnetic-resonance transmitting module includes a transmitting-end Bluetooth-communication and control module and at least two magnetic-resonance transmitting channels. Each magnetic-resonance transmitting channel includes a direct current/direct current (DC/DC) regulator module, a radio-frequency power amplifier source, a matching network and a magnetic-resonance transmitting antenna which are connected sequentially. The magnetic-resonance receiving module includes a receiving-end Bluetooth-communication and control module, a power synthesis and protocol module and at least two magnetic-resonance receiving channels. Each magnetic-resonance receiving channel includes a magnetic-resonance receiving antenna, a receiving-antenna matching network, a rectifier and filter module, a primary regulator and filter module and a secondary regulator and filter module which are connected sequentially. The magnetic-resonance transmitting antenna is coupled with the magnetic-resonance receiving antenna in one-to-one correspondence.
