Description

This evaluation kit and reference design implements the AMC130x reinforced isolated delta-sigma modulators along with integrated Sinc filters in the C2000™ TMS320F28377D Delfino™ microcontroller. The design provides an ability to evaluate the  performance of these measurements: three motor currents, three inverter voltages and the DC Link voltage.  Provided in the kit is firmware to configure the Sinc filters, set the PLL frequency and receive data from Sinc filters. A versatile run-time GUI is also provided to help the user validate the AMC130x performance and supports configuration changes to Sinc filter parameters in the Delfino controller.

Features
  • Isolated shunt feedback measurements of 3-phase motor currents and voltages using the new AMC130x reinforced isolated delta-sigma modulator
  • Integrated Sinc3 digital filters using new C2000™ F2837xD Dual-core Delfino™ microcontroller
  • Calibrated accuracy of ±0.2%, uncalibrated accuracy <2%
  • <4uSec response time for fault protection
  • Run-time GUI for complete performance analysis of modulator clock, sinc filter parameters, and currrent and voltage waveforms
  • Tested for IEC61800 (EMC requirements)
