Transient-Voltage Response
Pages 28

Transformers are normally used in systems to change power from one voltage (or current) to another.

This is often driven by a desire to optimize the overall system characteristics, e.g., economics, reliability,

or performance. To achieve these system goals, a purchaser must specify-and a designer must

configure-the transformer to meet a desired impedance, voltage rating, power rating, thermal charac-

teristic, short-circuit strength, sound level, physical size, and voltage-withstand capability. Obviously,

many of these goals will produce requirements that are in conflict, and prudent compromise will be

required. Failure to achieve an acceptable characteristic for any of these goals will make the overall

transformer design unacceptable. Transformer characteristics and the concomitant design process are

outlined in the literature [1-4].
