Embodiment 1

[0064] In this embodiment, a typical power supply tuning method of a wireless power supply device includes:

[0065] The receiving end control circuit monitors the power output circuit, and when the power output value of the power output circuit is lower than a threshold value, the receiving end control circuit sends a tuning signal to the transmitting end through the receiving end coil;

[0066] After the transmitter control circuit receives the tuning signal through the transmitter coil, it controls the transmitter tuning circuit to adjust the eigenfrequency of the transmitter coil, so that the power output value of the power output circuit is the highest, reaching the first highest value;

[0067] The receiving end control circuit adjusts the eigenfrequency of the receiving end coil through the receiving end tuning circuit, so that the electric energy output value of the power supply output circuit is the highest and reaches the second highest value.

[0068] The specific p...

Abstract

The invention provides a wireless power supply device and a tuning method thereof. A transmitting end control circuit and a receiving end control circuit are added at a transmitting end and a receiving end in the wireless power supply device respectively; when the tuned resonance frequency of the transmitting end and the receiving end are influenced by the specific environment where the wireless power supply device is applied, the receiving end control circuit and the transmitting end control circuit automatically adjust the eigenfrequency of a receiving end coil and the eigenfrequency a transmitting end coil, the purpose of tuning is achieved, the transmission efficiency of wireless power energy is improved, and the normal work of power supplied equipment is guaranteed.

Description

technical field [0001] The invention relates to the field of wireless power supply, in particular to a wireless power supply device and a tuning method thereof. Background technique [0002] As the application of wireless sensors becomes more and more popular, many equipment or devices that are difficult or impossible to measure by using wired methods can be easily measured by using wireless sensors. However, there is a problem of power supply when using wireless sensors. Generally, wireless sensors are powered by batteries. Such wireless sensors cannot perform real-time monitoring of equipment, and can only perform interval measurement to ensure that the battery’s power can make the sensor work for a long enough time. [0003] However, the emergence of Wireless Power Transmission (WPT) has made it possible to continuously supply power to wireless sensors. The existing wireless power transmission is divided into three implementation methods in principle, microwave / laser met...
