Description

Technical field [0001] The invention relates to a signal multi-stage amplification type wireless power transmission device, in particular to a long-distance, electromagnetic resonance type, and a multi-stage amplification type wireless power transmission device with convenient frequency adjustment. Background technique [0002] In recent years, with the continuous improvement of people's living standards and the gradual deepening of exploration of the material world, people have also placed new requirements on the transmission method and quality of electrical energy. Traditional electric energy transmission is mainly carried out by direct contact of wires or conductors. Sparks, sliding wear, carbon accumulation, and exposure of live conductors caused a series of problems. Wireless power transmission is a technology that uses radio to transmit electrical energy. It was first proposed by Nikola Tesla. Compared with the traditional power transmission method, there is no direct elect...

Problems solved by technology

However, most of the existing wireless power transmission systems at home and abroad are non-adjustable power supply systems, and some wireless power transmission systems use redundant control chips and algorithms to achieve adjustable frequency in some frequency bands. However, these systems have poor applicability and control circuits. The algorithm is cumbersome and the operation is very complicated, the cost is very high, and it is less and less favored in engineering applications
