TIDA-00601, Multi-phase Energy Measurement with Isolated Shunt Sensors Reference Design

TIDA-00601, Multi-phase Energy Measurement with Isolated Shunt Sensors Reference Design. The TIDA-00601 design implements a Class 0.5% three-phase energy measurement system with isolated shunt sensors. The isolation is achieved through the use of isolated delta-sigma modulators that have output circuitry capacitive isolated from input circuitry. An energy measurement SoC takes the different bit-streams from the isolated modulators and uses its on-board digital filters to produce ADC sample readings. The energy measurement SoC is also used for sensing voltages, calculating metrology parameter values, driving the board's LCD and communication to a PC GUI via the board's isolated RS-232 circuitry
