Software checking of audio transformers manufacturability

Abstract

Audio transformers seem to be quite omitted in the audio circuits design although they can be useful for their capability of noise and impedance optimization. However it is understandable that the circuit designers try to avoid them for their disadvantages, for example high price, bulky dimensions and complex design, there are still several applications in which the transformers can play important role. Because one of the disadvantages is that for each application there usually occur demands for a specific transformer, that must be designed and manufactured, usually in small series, the authors decided to search for a way how to make the transformer design easier. Therefore in this paper a simple algorithm of checking whether the calculated transformer is manufacturable or not is presented. The algorithm is created in Maple mathematics instrument and provides visualization of the dependences among the particular transformer parameters.
