Design of Contactless Wireless Power Supply System in Rotating Environment
A contactless wireless power supply solution based on magnetically coupled resonant type is proposed to meet the demand for power supply to the internal real-time monitoring equipment during the design and testing of rotating mechanical equip-ment such as marine gas turbines,and to overcome the problems of wiring difficulties and wear and overheating caused by the use of power supply slip rings in such rotating environments.After Simulink simulations are performed to verify the feasibility,the trans-mission efficiency of the wireless power supply scheme is tested experimentally in relation to different loads,distances and rotation-al speeds.The test results show that this solution can achieve stable and efficient transmission of 15 W energy at a designed distance of 10 mm,with an efficiency of more than 69%,and there is no significant impact on this wireless energy transmission solution at 7000 RPM.
