Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and relates to a constant current output wireless power transmission system capable of improving anti-offset capability. Background technique [0002] Wireless Power Transmission (WPT) technology, referred to as WPT technology, is a wireless transmission of electric energy using loosely coupled transformers. The coupling mechanism is a key part to realize wireless energy transfer, and has a great influence on a series of indicators such as the offset capability and energy transmission distance of the wireless energy transfer system. [0003] The main composition and working process of the existing wireless power transmission system are as follows: the power frequency alternating current is rectified into direct current, and then the direct current is reversed into high frequency alternating current after passing through the inverter. Frequency alternating magnetic field; the ...
