This paper deals with a numerical model of orthogonal-core transformers for use in spice. The model was devised on the basis of the magnetic circuit of the orthogonal-core with the saturation and hysteresis effects. Using the numerical model, the behavior of the dc-ac converter constructed with the orthogonal-core transformers and square-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 dc-ac converter taking account of nonlinear characteristics of the orthognal-cores and semiconductor devices used in the converter.
