Preface:

This is the first edition of CSA Standard CAN/CSA-CEI/IEC 61000-4-17, Electromagnetic compatibility (EMC) — Part 4-17: Testing and measurement techniques — Ripple on d.c. input power port immunity test, which is an adoption without modification of the identically titled CEI/IEC (Commission Électrotechnique Internationale/International Electrotechnical Commission) Standard 61000-4-17 (first edition, 1999-06), including Amendment 1:2001.

This Standard was reviewed for Canadian adoption by the CSA Subcommittee on Low Frequency Electromagnetic Compatibility, under the jurisdiction of the Technical Committee on Electromagnetic Compatibility of Low Voltage Equipment and the Strategic Steering Committee on Power Engineering and Electromagnetic Compatibility, and has been formally approved by the Technical Committee. A list of the members of the Technical Committee is available upon request. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada.

Scope:

This part of IEC 61000 defines test methods for immunity to ripple at the d.c. input power port of electrical or electronic equipment.

This standard is applicable to low-voltage d.c. power ports of equipment supplied by external rectifier systems, or batteries which are being charged.

The object of this standard is to establish a common and reproducible basis for testing, in a laboratory, electrical and electronic equipment when subjected to ripple voltages such as those generated by rectifier systems and/or auxiliary service battery chargers overlaying on d.c. power supply sources.

This standard defines

• test voltage waveform;
• range of test levels;
• test generator;
• test set-up;
• test procedure.

The test described hereafter applies to electrical or electronic equipment and systems. It also applies to modules or subsystems whenever the equipment under test (EUT) rated power is greater than the test generator capacity specified in clause 6.

This test does not apply to equipment connected to battery charger systems incorporating switch mode converters.

This standard does not specify the tests to be applied to particular apparatus or systems. Its main aim is to give a general basic reference to IEC product committees. These product committees (or users or manufacturers of equipment) remain responsible for the appropriate choice of the test and the severity level to be applied to their equipment.

Dedicated test procedures are in use for testing specific categories of electrical or electronic equipment, e.g. equipment connected to d.c. supply network of telephone switching centres; the related product committees should evaluate the relevance and applicability of the test procedure specified in this basic standard.
