About This Item

 

Full Description

Scope

This standard pertains to transformers and inductors of both the saturating and non-saturating type that are used in electronic power conversion equipment. Power conversion equipment includes items known as inverters, converters, power conditioners, switching power supplies, switched mode power supplies, and the like. These items are mostly devices used to change dc power from one voltage to another, to change dc power to ac, and to change ac power of one frequency to another frequency. This equipment is best described as utilizing transistors, silicon controlled rectifiers (SCRs), or other similar devices that switch power on and off at a high rate in order to achieve the power conversion or regulation desired. Therefore, this standard covers the various transformers and inductors that are used in any of the above mentioned equipment or devices, except for transformers operated directly from the mains.

Abstract

New IEEE Standard - Inactive-Reserved. Transformers and inductors of both the saturating and non-saturating type are covered. The power transfer capability of the transformers and inductors covered ranges from less than 1 W to the multi-kilowatt level. The purpose is to provide a common basis between the engineers designing power conversion circuits and the engineers designing the transformers and inductors used in those circuits. Apparatus used in equipment for high-voltage power conversion for distribution by electric utilities is not covered.
