Abstract
A high-power induction-type power supply system includes a supplying-end module consisting of a supplying-end microprocessor, a power driver unit, a signal analysis circuit, a coil voltage detection circuit, a display unit, a power supplying unit, a resonant circuit and a supplying-end coil, and a receiving-end module consisting of a receiving-end microprocessor, a voltage detection circuit, a rectifier and filter circuit, an amplitude modulation circuit, a protection circuit breaker, a voltage stabilizer circuit, a DC-DC buck converter, a resonant circuit and a receiving-end coil. By means of single bit data analysis to start up power supply, sensing signal transmitting time during standby mode is minimized. Subject to asymmetric data signal data encoding and decoding system to recognize data code, power loss is minimized during synchronous transmission of power supply and data signal, and a high capacity of fault tolerance is achieved.
