Coming, the appearance of fractal theory provides new physical interpretation for fractional calculus theory, so that its rapid development is promoted,
Development especially in the fields such as high molecular material and nano material is especially rapid.Since integer rank calculus is only to nature
A kind of approximation of boundary's physical phenomenon is explained and can not accurately be described, therefore fractional calculus starts to be paid attention to, and gradually answers
For engineering and control field.In recent years, fractional calculus theory is opened in Circuits and Systems and field of power electronics
Beginning is studied and is applied, and since traditional resonant transformation technology is theoretical based on integer rank calculus, and is based on fractional order
Calculus theory realizes that this field of resonant transformation has not been studied and applies.
In view of the advantage for carrying out Parameters Optimal Design currently with fractional calculus theory, it is not applied to resonance also
Converter technique field, it is therefore necessary to propose a kind of fractional order D class parallel resonance device.
