TIDM-2PHASE-SUBMTR-FW2 Reference Design

Texas Instruments

Two Phase Embedded Metering Firmware Upgrade

Description

This design is the upgard of firmware of the original TIDM-2PHASE-SUBMTR. This upgrade add functionalities and flexibility to the original firmware including : I2C communication capability: fundmental voltage and current measurment: voltage anc current THD measurement: reengineering of the the architecture allows flexible re-assignment of ADC channels.

Features
  • •Measures AC frequency: RMS voltage: RMS current; Fundmental voltage: fundamental current: P active: P reactive: P apparent: power factor in better than 0.5% accuracy•Flexible re-assignemnt of ADC channels •I2C (slave mode) communication capability
Applications
  • Electricity meter
