Embodiment Construction

[0021] The invention provides a wireless energy transmission efficiency test system when conditions such as different distances, offsets, and offset angles change.

[0022] Such as figure 1 As shown, the wireless energy transmission efficiency test system includes an input power supply, a transmitter controller, a transmitter coil, a receiver coil, a receiver controller, a load, a mobile device and a host computer.

[0023] The input power supplies power for the wireless energy transmission efficiency test system, which can be DC power or AC power;

[0024] The transmitter controller transforms the input power into the high-frequency signal required by the wireless energy transmission system through DC-AC, AC-AC or AC-DC-AC; the transmitter controller also collects the voltage and current of the input power and sends it to Host computer, and the host computer can set the working frequency of the controller at the sending end;

[0025] The transmitter coil is connected to the...

Abstract

The invention provides a wireless energy transmission efficiency testing system. A wireless energy transmission efficiency test can be conducted when different conditions of the work efficiency, load impedance, distance, offset, deviation angle and the like change, by setting sending end coil working frequency and the output end coil load impedance of a wireless energy system, information of the relative positions of the wireless energy sending end coil and receiving end coil, the voltage and the current of the sending end coil, the output voltage and the output current of the receiving end coil and the like are collected in real time, and the transmission efficiency on different conditions is obtained through processing. On one hand, a designer can be helped to study the influence of all external factors on the wireless energy transmission efficiency, and system design can be better implemented; on the other hand, it is beneficial for an existing wireless energy transmission device to conduct a standardized test.

Description
