About This Item
IEC 62747:2014/AMD1:2019 defines Amendment 1 to the terminology for voltage-sourced converters (VSC) used in high-voltage direct current (HVDC) systems. For engineering, procurement, and compliance teams, IEC 62747:2014/AMD1:2019 is relevant when precise language is needed to support technical review, documented evaluation, and conformity assessment work around HVDC converter projects. By updating terminology connected to VSC-based HVDC systems, it helps improve consistency across specifications, design documents, test records, and regulatory preparation.
Overview of IEC 62747:2014/AMD1:2019
This amendment supports the parent document, IEC 62747:2014, by refining terminology used for voltage-sourced converters in HVDC applications. Its practical value is in helping engineers, laboratories, and specification writers use a common technical vocabulary when discussing converter functions, system boundaries, and related performance considerations. In project documentation and technical validation workflows, consistent terminology can reduce ambiguity during design review, procurement comparison, and verification activities. The document is most useful where HVDC converter technology is being assessed, specified, or documented in a controlled engineering environment.
Compliance applications of IEC 62747:2014/AMD1:2019
IEC 62747:2014/AMD1:2019 may be used in HVDC system engineering, converter station documentation, test planning, and supplier communication where terminology must remain aligned across teams. It is particularly relevant in technical assessment, quality workflows, and conformity assessment preparation for voltage-sourced converter projects. Organizations involved in electrical equipment evaluation, system integration, or laboratory evaluation can use the amendment to support clearer reporting and fewer interpretation issues. In procurement and specification reviews, it also helps maintain operational consistency between contract language and engineering documentation.
Importance of compliance with IEC 62747:2014/AMD1:2019
Using the terminology defined and updated in IEC 62747:2014/AMD1:2019 helps reduce misunderstanding in safety-related and performance-related communication for HVDC converter systems. Clear terminology supports more reliable testing workflows, better traceability in technical documents, and smoother coordination between design, verification, and procurement teams. For organizations preparing compliance evidence, consistent wording can improve the quality of engineering documentation and limit avoidable rework during regulatory or customer review. In complex power conversion projects, this kind of alignment is often important for risk management and interoperability.
