Description

This Special Measurement provides parameters for the measurement of Ripple on the output of a switching power supply.

Specifications/Details

Spec Level:  N/A

App Update Level/Date:      1.0, October 2013

Minimum M1 version required:      v7.00

Measurements Made:

  • RMS Voltage (over only complete cycles of the switching waveform)
  • Peak voltage (maximum absolute value)
  • Crest Factor

Statistics Produced:

  • RMS Voltage
  • Peak voltage maximum
  • Crest Factor (Peak / RMS)

Assumptions:

  • Can be used to measure either Voltage or Current waveforms
  • Voltage (V) or Current (I) probes should be placed as shown below:

Features

  • Not Applicable for this App

Comments

  1. This App is also used to measure the listed parameters for Power Quality measurements, using the same probe placements as specified for the Power Quality App.
  2. ASA is in the process of adding a variety of power-related Measurement Apps, to be followed shortly by a complete Power Application to organize and expand these measurements.
