In this paper, the optimum design technique for a single-ended forward DC-DC converter is given. A transformer of a converter with two output circuits is used as a demonstration example. To minimize the weighted sum of the power loss and the weight of the transformer, subject to the performance index constraints, a mathematical model, based on the ideal wave forms and the theoretical formulae of a converter, is derived. The Augmented Lagrangian Penalty Function Technique is adopted to form a CAD program written...

In this paper, the optimum design technique for a single-ended forward DC-DC converter is given. A transformer of a converter with two output circuits is used as a demonstration example. To minimize the weighted sum of the power loss and the weight of the transformer, subject to the performance index constraints, a mathematical model, based on the ideal wave forms and the theoretical formulae of a converter, is derived. The Augmented Lagrangian Penalty Function Technique is adopted to form a CAD program written in FOETKAN-IV. The calculated results, the graphical representations, the discussion and the conclusion regarding the optimum design are presented.

In this paper the application of the duality principle to the DC-to-DC switching converters are investigated. Each of the converter circuit branches may contain a power switching transistor, a diode or a winding of an isolated transformer in addition to general circuit components. The duality rules and steps for generating the dual network of the DC isolated converter is stated as in the examples of the SEPIC converter and the flyback converter with multiple outputs, and the isolation feature is still hold in the duals. By applying the duality rules and steps presented in the paper, the dual network of any planar converter circuit including the quaY-resonant converter can be obtained simply and readily.
