Semiconductor converters. General requirements and line commutated converters. Application guide | Status: Current

1 Scope This part of IEC 60146, which is a Technical Report, gives guidance on variations to the specifications given in IEC 60146‑1‑1:2009 to enable the specification to be extended in a controlled form for special cases. Background information is also given on technical points, which facilitates the use of IEC 60146‑1‑1:2009. This document primarily covers line commutated converters and is not in itself a specification, except as regards certain auxiliary components, in so far as existing standards may not provide the necessary data. This document will not take precedence on any product specific standard according to the concept shown in IEC Guide 108. IEC Guide 108 provides the information on the relationship between horizontal standards and product publications.
