Power analyzer

Block diagram

Overview

Our integrated circuits and reference designs help you create high-precision power analyzers for accurate efficiency and power waveform analysis of motors, inverters, power conditioners and power supplies.

Design requirements

    New generation power analyzer designs require:

  • High voltage and current measurement capabilities.
  • Wide frequency BW to capture high number of harmonics.
  • High-accuracy measurement capabilities for high and low power factor conditions.
  • Multi-unit synchronization for simultaneous measurement of multiple circuits.
