The invention provides an adjusting device and an adjusting method for a two-way radio-frequency power supply. The adjusting device comprises an amplitude detection module, a phase detection module and an adjusting module, wherein inductors of the two-way radio-frequency power supply are respectively connected with coupling capacitors; two voltage amplitudes are respectively converted into a current signal, and then, the current signal is converted into a voltage signal, and therefore the two voltage amplitudes are obtained; then, the two voltage amplitudes are respectively sent to differential amplifiers, and amplitude difference is sent to the adjusting module; the side parts of the inductors of the two-way radio-frequency power supply are respectively provided with an antenna; phase signals obtained by the antennae are respectively sent to a phase discriminator; phase difference is sent to the adjusting module; the adjusting module is used for adjusting the two-way radio-frequency power supply according to the received amplitude difference and the received phase difference. The adjusting device provided by the invention has the advantages of being high in precision, fast in response, and the like.
