Research on transmission performance of the contactless transformer

The contactless transformer is the core of the Contactless Electrical Energy Transmission (CEET) system, and it forms a loosely coupled system. The transmission performance of contactless transformer is relatively low, but the method of capacitor compensation can change its performance. Using the mutual inductance model of contactless transformer to analyze the circuit structure, we can get different capacitor compensation methods of primary and secondary. In the resonant condition compared with the non-compensation circuit, the output power of capacitor compensation circuit is significantly improved. By means of Multisim simulation software, we can verify the conclusion by the capacitor compensation experiment.
