The invention discloses an anti-offset constant-voltage constant-current output compensation structure and a parameter construction method thereof. The anti-offset constant-voltage constant-current output compensation structure comprises a voltage-stabilizing direct-current power supply, a full-bridge inverter circuit, a synchronous rectification circuit, a primary side compensation structure, a primary side transmitting coil, a secondary side receiving coil, a secondary side compensation structure and an equivalent load, two compensation structures are combined by switching off the switch to select different resonator devices, the first compensation structure has a load-independent constant current output characteristic, the second compensation structure has a load-independent constant voltage output characteristic, and the constant voltage and constant current are switched through the switch. The system works in a constant-current output mode at the initial charging stage of small equivalent resistance of the battery, when the equivalent resistance of the battery is gradually increased, the system works in a constant-voltage output mode, and when the primary transmitting coil and the secondary receiving coil deviate, the system works in a constant-voltage output mode. The voltage and the current can still keep the same voltage and the current in alignment within a certain range, and when the voltage and the current exceed the certain range, the system can still keep stable automatically, and the performance is stable.

    一种抗偏移恒压恒流输出的补偿结构及其参数构建方法,包括稳压直流电源、全桥逆变电路、同步整流电路、原边补偿结构、原边发射线圈、副边接收线圈、副边补偿结构和等效负载;通过开关关断对不同谐振器件的选择,组合成两种补偿结构,第一补偿结构具有负载无关的恒流输出特性,第二补偿结构具有负载无关的恒压输出特性,通过开关在恒压与恒流模式之间切换,在电池等效电阻较小的充电初始阶段系统工作在恒流输出模式,在电池等效电阻逐渐增大时,该系统工作切换到恒压输出模式,当原边发射线圈与副边接收线圈发生偏移时,电压与电流在一定范围内仍然可以保持与对准时同样的电压与电流,当超过一定范围时,该系统仍然可以自动保持稳定,性能稳定。
