Example Embodiment
[0052] Example one
[0053] Please refer to figure 1 , Which is a schematic diagram of the inductive wireless power transmission system in this embodiment. Such as figure 1 As shown, the inductive wireless power transmission system includes: a transmitting end part and a receiving end part. The transmitting end part includes: a power factor correction module 1 (or PFC module) connected in sequence, and a three-phase bridge inverter at the transmitting end. Module 2, transmitting end resonance module 3, transmitting end sampling / driving module 4, and transmitting end control module 5. The transmitting end sampling / driving module 4 is also connected to the power factor correction module 1 and the transmitting end three-phase bridge, respectively The inverter module 2 is connected; the receiving end part includes: the receiving end resonant module 6, the receiving end three-phase bridge rectifier module 7, the receiving end sampling / driving module 8 and the receiving end control ...

[0073] Example two
[0074] Please refer to Figure 7 , Which is a schematic diagram of the application of the multi-adjustment parameter control method in the present invention. Such as Figure 7 As shown, the multiple adjustment parameter control method includes the following steps:
[0075] Using power factor correction voltage and current double closed-loop control power factor correction module 1;
[0076] All switches in the transmitting end resonant module 3 and the receiving end resonant module 6 (ie, the first switch Sp1, the second switch Sp2, the first receiving switch Ss1, and the second receiving switch Ss2) are controlled on and off;
[0077] The three-phase bridge inverter module 2 at the transmitting end and the three-phase bridge rectifier module 7 at the receiving end are controlled by phase shifting.
[0078] There are five system power adjustment parameters that can be changed based on the multi-adjustment parameter control method, including: PFC output DC voltage...
