The invention belongs to the technical field of wireless charging, and particularly discloses a wireless charging system with a strong anti-offset function and a parameter design method thereof. The wireless charging system comprises a direct-current power supply UD, a high-frequency inverter H, a primary side compensation inductor L0, a primary side compensation capacitor C0, a first transmitting coil LP1, a first primary side compensation capacitor C1, a second primary side compensation capacitor C2, a second transmitting coil LP2, a second receiving coil LS2, a first secondary side compensation capacitor C3, a secondary side compensation inductor L1, a second secondary side compensation capacitor C4, a first receiving coil LS1 and a rectifying circuit. A filter capacitor CF; and a load RL. The system has the beneficial effects that the output voltage of the system is not influenced by load change, the output voltage of the system is kept constant when the coil deviates, good anti-deviation capability is achieved, zero-phase-angle operation can be achieved, and the system efficiency is improved; a special magnetic coupler structure is used, so that the adverse effect of cross coupling on a system is effectively avoided, and the size of the magnetic coupler can be greatly reduced.
