About This Item
TS IEC 60050-551 is the part of the International Electrotechnical Vocabulary devoted to power electronics. As a vocabulary standard, it supports consistent use of technical terms for converters, switching devices, rectification, inversion, and the electronic control of electrical power, so that the same concepts are understood in the same way across documents and disciplines.
What power electronics terminology helps organise
Power electronics is the branch of electrical engineering concerned with converting, controlling, and conditioning electrical energy by means of semiconductor-based circuits. In practice, it underpins AC/DC conversion, DC/AC conversion, voltage and current regulation, motor drive control, and many energy-efficiency applications. A terminology standard in this field helps reduce ambiguity in specifications, training materials, technical literature, and cross-referenced standards.
How this section fits into the IEV structure
This standard belongs to IEC 60050, the International Electrotechnical Vocabulary, and is identified as a horizontal standard. That means it serves as a shared terminology reference across multiple kinds of equipment and applications rather than prescribing a single product category. Because power electronics sits at the intersection of electrical engineering and electronics, its terms are relevant to both power systems and electronic circuit design.
- It is a vocabulary document, not a test or performance standard.
- It focuses on consistent naming of power electronics concepts.
- It sits within the broader IEC 60050 terminology framework.
- The referenced edition is IEC 60050-551:1998.
