The invention relates to a constant-current constant-voltage IPT system capable of configuring charging voltage and charging current. The system comprises an inverter used for outputting an AC voltage source as input excitation of an LCL type compensation network; the LCL type compensation network is connected with the T type compensation network and enters a constant current charging mode, and the T type compensation network is connected with the rectifier; the LCL type compensation network and the T type compensation network are compounded to form an IPT constant current charging system capable of configuring charging current; when the load voltage rises to the switched threshold voltage, the LCL type compensation network is connected with the T '-type compensation network to enter a constant-voltage charging mode, and the T'-type compensation network is connected with the rectifier; the LCL type compensation network and the T 'type compensation network are combined to form an IPT constant voltage charging system capable of configuring charging voltage; the rectifier is connected with the charging load. According to the invention, the charging current and the charging voltage can be freely configured.
