摘要: The use of resolvers and resolver-to-digital (R/D) converters in industrial applications is increasing in the past few years. Meanwhile, as the need for high speed and high precision in Adjustable Speed Drives (ASD) is increasing imperiously, traditional analog R/D converters are replaced by digital R/D converters. Compare to traditional analog R/D converters, the advantage of using digital R/D converters is that it has high accuracy, good noise resistance, and low cost. Here, an improved R/D converter developed using FPGA codes is performed in this research. This proposed R/D converter utilizes synchronous detectors for signal demodulation, and A/D converters for analog to digital signal conversion, as well as built-in look-up table for angular data conversion. The result of this research shows the effectiveness of this proposed R/D converter system and is feasible to implement into the modern ASD and its applications.
