The Research of Contact-Less Power Transmission System Operating in the Closed High Hydraulic Environment

In this paper, a new type of AC-AC contact-less power transmission system based on the specific engineering environment is produced. A new loosely-coupled transformer structure and its working type are developed. Besides, a new set of high efficient based on the qusai-resonant technology is realized. Theoretical calculation and simulation software are used to prove its feasibility; a series of experiments are completed. Finally, the contact-less power transmission system functions well.
