  "textContent": "A device for controlling wireless charging output power based on a PWM integrating circuit includes a magnetic-resonance transmitting module and a magnetic-resonance receiving module. The magnetic-resonance transmitting module includes a wireless charging base, a Bluetooth master circuit, a DC/DC regulator circuit, a PWM integrating circuit, a radio-frequency power amplifier source, a radio-frequency current sampling circuit and a magnetic-resonance transmitting antenna. Both the radio-frequency power amplifier source and the magnetic-resonance transmitting antenna are mounted at the wireless charging base. The magnetic-resonance transmitting antenna is connected to the magnetic-resonance receiving module. The magnetic-resonance receiving module includes a cooling fin, a magnetic-resonance receiving antenna, a Bluetooth slave circuit, a receiving rectifier and regulator circuit and a charging control circuit. The magnetic-resonance receiving antenna, the receiving rectifier and regulator circuit and the charging control circuit are connected successively. The magnetic-resonance receiving antenna is arranged directly above the magnetic-resonance transmitting antenna.",
