Beschreibung
Zusammenfassung:	The invention relates to a wireless power transmission technology, in particular to a wide-range ZVS constant current/constant voltage bidirectional IPT system and a parameter design method thereof, a primary circuit of the system is provided with a primary converter, a primary compensation circuit and a primary coil, and a secondary circuit is provided with a secondary coil, a secondary compensation circuit, a secondary converter and a storage battery. The primary side converter is connected to a power grid and works in an inversion state according to a charging resonant frequency fc, the secondary side converter works in a rectification state, and energy is transmitted to the secondary side coil through the primary side coil so as to realize constant-current output wireless charging of the storage battery; when the storage battery is discharged, the secondary side converter works in an inversion state according to the discharging working frequency fd, the front end of the primary side converter is connected
