An approach to the design of energy storage reactors for DCtoDC switching power converters using ferrite structures
Abstract
The method for the design of energy storage reactors for dctodc power converters is outlined. With the dynamic equations of the power converter and the calculations of the total power losses in the reactor as a starting point, the approximate expression describing the required volume of the core is derived, and the optimal geometry of the magnetic circuit is found analytically. The method, for a given power stage specification and constant coefficients of the geometry of a normalized core series, uses a designerselected value of the difference between the operating temperature of the reactor's external surface and the ambient temperature as a major design constraint. The design procedure makes use of a family of coreloss characteristics. The boost type of power regulator is used as an example, yet the design technique may be applied to each of nine different dctodc power converters and is applicable to most core shapes and most modern magnetic materials.
