Problems solved by technology

[0005] 1. The transmission power of the transmitter is gradually approaching the rated power of the receiver, and the adjustment time is long, so it cannot be adjusted to the rated power of the load in real time;
[0006] 2. Since the load power is fed back through system-related parameter changes, etc., measurement errors will inevitably occur, which will affect the accuracy of system power matching

Abstract

The invention discloses a power adjustment method of a wireless power transmission system and a system thereof. The method comprises the following steps that a receiving end of the wireless power transmission system sends communication information comprising current load information to a transmitting terminal of the wireless power transmission system; the transmitting terminal of the wireless power transmission system searches a power parameter corresponding to the load information in an index table; the transmitting terminal of the wireless power transmission system emits power which matches with the power parameter to the receiving end of the wireless power transmission system. The transmitting terminal in the invention is switched to different power gear directly according to the communication information fed back by the different receiving ends so that control precision of the system is greatly increased and simultaneously adjustment time is shortened.

Description

technical field [0001] The present invention relates to the technical field of wireless power transmission, in particular to a power adjustment method and system for a wireless power transmission system. Background technique [0002] Wireless Power Transmission (WPT), also known as Contactless Power Transmission (CPT), is a technology for energy transfer by means of electromagnetic fields or electromagnetic waves. Generally, inductive coupling power transmission technology is used, through electromagnetic coupling to Non-contact way to transfer energy to the load, the principle is as follows figure 1 shown. [0003] The wireless power transmission system is divided into two parts: the transmitting end (primary side) circuit and the receiving end (secondary side) circuit. The transmitting end circuit mainly completes the conversion and transmission of electric energy, and the receiving end circuit mainly completes energy pickup and voltage regulation. The system uses the hi...
