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