Wireless Power and Communication Transmission for Industrial Robots

摘要

Mid-range resonant wireless power transfer (WPT) gained tremendous attention due to the higher efficiency. However, the relatively narrow transmission band has been simply drawn the technology back from being implemented in an application where the data and a power transmission are required. In this paper both the simulation and a practical implementation of a Strongly Coupled Magnetic Resonant (SCMR) system with a high frequency band for simultaneous data and power transmission is proposed. With this method communication and a power transmission can be transmitted in an industrial robot applications. Multiple TXand a single RXloop are placed between the joint of the robot in order to increase frequency spectre. The simulation has been developed in the theoretical analysis of equivalent circuits of the improved SCMR system. The analysis eventually leads to the factual parameters of a WPT system to provide its maximum efficiency for both wireless power and data transmission for an industrial robot. Besides the analysis has been validated with a comparison between the simulation results and practical implementation.
