The present inventions relates to a method for power self-regulation in a high-power induction type power source, wherein the PS module includes a PS microprocessor that is electrically connected to a PS driving unit, signal analysis circuit, coil voltage detection circuit, display unit, PS unit and earthing terminal respectively, and further connected with a resonance circuit and PS coil electrically through the PS driving unit, while the PR module contains a PR microprocessor electrically connected with a voltage detection circuit, breaker protection circuit, voltage stabilizing circuit, AM carrier modulation circuit, DC step-down transformer, rectifying filter circuit and resonance circuit respectively. While transmitting electric power, the PS module receives and analyzes data signals and then regulates the transmitted power through self-regulation programs in the microprocessor, thus achieving the purpose of power self-regulation for the PR module.
