Description

This design implements a high-accuracy single-phase embedded energy measurement application using MSP430AFE253. This EVM has built-in support for measuring AC voltage, current, active power, reactive power, apparent power, frequency, power factor, DC voltage, DC current, and DC active power. It has the ability to detect the input voltage to work in DC or AC mode. It is also equipped with the capability to compensate the effect of the wire resistance and the EMI filter capacitor so that the reading of voltage and power matches the reading of an external meter when EMI filter is connected to the input side. Designers who need to add energy measurement capability to their product will find this reference design a useful aide in quickly incorporating this feature.

Features
  • Measures AC frequency, RMS voltage, RMS current
  • Measures active, reactive, and apparent power plus power factor with 0.5% accuracy
  • Readings update every 4 AC cycles or 80ms
  • Automatic reporting measurements to UART
  • Automatic sensing and switching between AC and DC modes
  • Capable of EMI capacitor and wire resistance compensation
  • No separate DC calibration required"
