A study of communication system for power electronics controller using FPGA based hardware controller

In this paper, an new network communication system for power electronics controller to transmit the feedback signal from the sensors using FPGA based hardware controller was proposed. Based on 100BASE-TX network controller, customized UDP protocol was implemented to achieve high speed feedback communication between two FPGA controller. In the proposed method, communication protocol (OSI reference model) and LAN-controller operation were handled using FPGA, highspeed processing was realized. As the result, feedback control signal can be transferred through the communication line which result in the reduction of the cables in the power electronics system. The performance of the proposed system was verified through simulations and experiments.
