Problems solved by technology
However, since the impedance characteristics of the load equipment to be driven in practical applications and the required power supply conditions are different, the use of AC-DC circuits with static impedance matching will lead to poor adaptability of the acoustic carrier wireless transmission system, and cannot maintain efficient power supply for different loads. can
Poor adaptability, complex debugging, and unstable power supply efficiency make it difficult for the acoustic carrier wireless transmission system to be commercialized

Description
technical field [0001] The invention relates to the field of acoustic carrier wireless transmission, in particular to an adaptive AC-DC conversion device and method for acoustic carrier wireless transmission. Background technique [0002] With the development of science and technology, instruments and equipment are widely used in various fields, and the breadth of spatial distribution is also increasing. It is difficult to provide wired power supply for instruments and equipment to meet all application scenarios. Therefore, wireless power supply technology has been paid attention to, and the most common one is wireless energy transmission technology based on electromagnetic coupling. However, the application of this technology for wireless energy transmission will be affected by the electromagnetic shielding effect, and cannot be applied to wireless energy transmission in scenarios such as underwater, inside and outside closed metal boxes. Therefore, the acoustic carrier wi...
