平面旋转机构监测器无线供电系统稳定性研究OA

Taking the planar rotation mechanism as an example,a magnetic coupling wireless power transmission system was designed and studied from two perspectives:the spatial structure of the coils and the resonant compensation circuit.This system aimed to reduce the voltage fluctuations caused by significant changes in mutual inductance between the coils during rotation and ensure system stability.Regarding the spatial structure of the coils,four coils were fixed on a stationary plane at the transmitter end,while two coils were used at the receiver end and fixed on the plane of the rotation mechanism to ensure that they could induce a certain amount of current during rotation.For resonant circuit compensation,an LCC/S-type compensation network was adopted.The current at the transmitter end is only influenced by the compensating inductance and input voltage,further enhancing the coils'resistance to offset.This approach provides significant advantages in terms of power transmission and efficiency improvement.Finally,a simulation and experimental platform was established to validate the design.The experimental results demonstrated that using two receiver coils and the LCC/S topology resulted in improved output voltage,power,and efficiency while maintaining stability to a certain degree.
