Matched Transformers for Synchro and Resolver Applications

摘要

Transformer pairs in Scott Tee and similar transformer arrangements have been used for some considerable time inprecision synchro/resolver angular measuring gear and in synchro to digital converters. Literature on the subject oftransformer requirements is, however, scant or non-existent.1,2This paper describes the basic principle oftransformer operation and develops a design approach which, although aimed primarily at the minimisation oftransformer hardware size, still maintains the required level of angular accuracy. The method applies to transformersutilised in mobile systems, particularly transformer arrangements working under loaded conditions.
