How to design 1-phase shunt electricity meters using standalone metrology ADCs

As processing requirements for electricity meters gradually increase, it becomes increasingly difficult to find one device that meets both the processing requirements for adding advanced metrology features to smart meters while also accurately sensing metrology parameters, such as RMS voltage, RMS current and active power.  To deal with this design challenge, one option is to use a separate metrology microcontroller and a standalone ADC.

Current sensor and metrology architecture options

This section compares two types of current sensors used in electricity meters: current transformers and shunts.  In addition, it discusses three different architectures for sensing the voltage and current samples used to calculate the metrology parameters.  These architectures include a SoC-based architecture, AFE-based architecture, and ADC-based architecture.

Introduction to TIDA-010036 reference design

This section provide an overview of the TIDA-010036 reference design, which uses the ADS131M04 delta sigma standalone ADC for sensing the voltage and current necessary to calculate metrology parameters.  The TIDA-010036 design targets Class 0.5 single-phase two-wire meters with shunt current sensors and has a compact, magnetically immune cap-drop power supply to power the design from AC mains.

TIDA-010036 hardware design

This section provides an overview of the hardware used in the TIDA-010036 design, which includes the circuits used to translate the Mains voltage and current to the voltage waveform sensed by the ADS131M04.  In addition, it covers the TPS7A78-based cap-drop power supply used in this design.
