AC Drive Position Feedback

AC Drive Position Feedback System Solutions from Texas Instruments


Robust and accurate rotor position feedback is essential for performance and reliability of variable speed AC drives. AC drive position feedback is connected to an analog/digital position sensor and needs to be designed for accurate and robust high-speed low latency data transmission with high EMC immunity. Often interfaces need to support multiple encoder protocols with configurable output voltage to mitigate the different types of position feedback sensors. The following TI solutions are available to help solve these system design challenges:

  • High data rate, low latency and robust interface solutions for incremental and absolute encoders such as EnDat2.2, BiSS and HIPERFACE DSL
  • High performance analog and highly integrated solutions for precision resolver and Sin/Cos encoder measurement
  • Efficient and low noise power solutions with protection features for position feedback systems
  • Robust industrial interface solutions that help meet and exceed IEC61800-3 EMC Immunity
