Utilization of Xilinx FPGA Built-in Analog-To-Digital Converter for Data Acquisition in Power Electronics Converter

Abstract

Power Electronics Multilevel Converters require a large number of high speed current and voltage measurements. In this work, we are utilizing the Xilinx FPGA internal built-in Analog-to-Digital Converter for this purpose. To increase the total number of available analog inputs, an external multiplexer is used. Therefore, an XADC external multiplexer controller is proposed to rotate these analog inputs for conversion. Additionally, this controller will coordinate data storage for each data conversion. The feasibility of the proposed XADC external multiplexer controller is evaluated experimentally.
