Embodiment 1

[0053] Please refer to figure 1 , which is a schematic diagram of the inductive wireless power transfer system in this embodiment. Such as figure 1 As shown, the inductive wireless power transfer system includes: a transmitting end part and a receiving end part, and the transmitting end part includes: a sequentially connected power factor correction module 1 (or PFC module), a three-phase bridge inverter at the transmitting end Module 2, transmitter resonant module 3, transmitter sampling / driving module 4 and transmitter control module 5, the transmitter sampling / drive module 4 is also connected with the power factor correction module 1 and the transmitter three-phase bridge respectively The inverter module 2 is connected; the receiving end part includes: a receiving end resonant module 6 connected in sequence, a receiving end three-phase bridge rectification module 7, a receiving end sampling / driving module 8 and a receiving end control module 9, and the receiving end sampli...

Embodiment 2

[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 multi-adjustment parameter control method includes the following steps:

[0075] Adopt power factor correction voltage and current double closed-loop control power factor correction module 1;

[0076] All switches in the resonant module 3 at the transmitting end and the resonant module 6 at the receiving end are controlled on and off (ie, the first switch Sp1, the second switch Sp2, the first receiving switch Ss1, and the second receiving switch Ss2);

[0077] The three-phase bridge inverter module 2 at the transmitting end and the three-phase bridge rectifying 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, specifically including: PFC out...

Abstract

The present invention provides an inductive wireless electric energy transmission system and a multi-adjustment parameter control method. Based on the design of a transmitting end portion and a receiving end portion in the inductive wireless electric energy transmission system and the combination of mutual cooperation of the transmitting end portion and the receiving end portion and five power adjustment parameters, a vehicle power battery constant current and constant voltage charge function is commonly completed to achieve optimal control of the transmission power and the transmission efficiency of the system; the inductive wireless electric energy transmission system can achieve four working modes to allow the coils of the transmitting end portion and the receiving end portion to be better paired, the two coil structures have good compatibility and interoperability. Besides, a three-phase bridge inverter module of the transmitting end and a three-phase bridge rectifier module of thereceiving end employ a three-phase bridge structure instead of a traditional H-bridge structure, so that when one of the inverter bridge and the rectifier bridge in the system has faults, the systemstill performs power transmission and has good fault tolerance through corresponding control.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an inductive wireless power transmission system and a multi-adjustment parameter control method. Background technique [0002] The vehicle-mounted inductive wireless power transfer system has developed rapidly due to its advantages of charging convenience, charging safety and environmental adaptability. However, the current vehicle-mounted inductive wireless power transfer system still has the following technical deficiencies: [0003] (1) Compatibility of the coil structure between the vehicle end and the non-vehicle end: When the vehicle end part is provided by supplier A, and the non-vehicle end part is provided by supplier B, the two need to cooperate with each other to complete the wireless charging function, and the coil structure is compatible Sex is something that has to be addressed. [0004] (2) The problem of low system fault tolerance: Traditional inductive wirel...
