Research On The Circuit Structure And Mechanism Of Wire-less Power Transfer Based On Magnetic Resonances

Coupled resonant type contactless power transmission is a use of near zonemagnetic field through the strong magnetic coupling to achieve a kind of powertransmission, the transmitting terminal and the receiving terminal at the same timeresonance to achieve a new wireless energy transmission technology, not only thetransmission distance can reach nanometer level range, and previous use of microwave,laser and induction methods, the method can have larger power transmission and hightransmission efficiency, create a new type of energy transmission way, have importantscientific research value and significance.Secondly, the coupling resonance type contactless power transmission circuittopologies are analyzed, the transmitting end and the receiving end of the resonant modesare determined.Finally, the contactless power transmission experimental structure is analyzed indetail, including the transmitting terminal of the rectifying inverse module, a drivingcircuit module, a transmitter coil and a receiver coil specific parameters. Each circuitmodule debugging after the stability of structures of the contactless power transmissionexperiment platform.The success of the experimental light receiving coil20W incandescent light bulb, themaximum transmission efficiency can reach40%, and records the different distancereceiving end voltage of the experimental data with the experimental waveform, throughexperiments verify the coupling resonance type contactless power transmission feasibility,to lay the foundation for follow research.
