This module discusses the advantages of using a TPS7A78 AC voltage regular for implementing a cap-drop power supply. This is the second of two modules for the “TIDA-010036 hardware design” section of the “How to design 1-phase shunt electricity meters using standalone metrology ADCs” training series.
1Current sensor and metrology architecture options (2)
This section compares two types of current sensors used in electricity meters: current transformers and shunts.
2Introduction to TIDA-010036 reference design (2)
An overview of the TIDA-010036 reference design, which uses the ADS131M04 delta sigma standalone ADC for sensing the voltage and current.
3TIDA-010036 hardware design (2)
An overview of the hardware used in the TIDA-010036 design, including the circuits used to translate the Mains voltage and current.
4Designing software for 1-phase electricity meters that use standalone ADCs (2)
This section covers the initialization code and algorithms that can be used to calculate metrology parameters in a single-phase system.
5ADS131M04 current detection mode for detecting neutral removal tampering (2)
This section discusses current detection mode, which is a special low-power mode of the ADS131M04 standalone ADC.
6Calibration and metrology accuracy results (2)
This section discusses the procedure used to calibrate the TIDA-010037 design and the results obtained with this design.
A summary of the entire “How to design 1-phase shunt electricity meters using standalone metrology ADCs” training series.
