Aspicemodel of orthogonalhyphen;core transformers

摘要

This paper deals with a numerical model of orthogonalhyphen;core transformers for use inspice. The model was devised on the basis of the magnetic circuit of the orthogonalhyphen;core with the saturation and hysteresis effects. Using the numerical model, the behavior of the dchyphen;ac converter constructed with the orthogonalhyphen;core transformers and squarehyphen;wave transistor choppers was analyzed. The calculated values and measured ones show a good agreement. The method presented here is suitable for the circuit analysis and design optimization of the dchyphen;ac converter taking account of nonlinear characteristics of the orthognalhyphen;cores and semiconductor devices used in the converter.
