Chapter 21 - Magnetic Parts Editor

Abstract

The Magnetic Parts Editor (MPE) is used for the design of transformers and inductors in switched mode power supply topologies. In particular, the MPE provides a complete transformer design cycle for forward converters, both single and double switch, and a flyback converter operating in discontinuous conduction mode. At the end of the design cycle, the MPE generates a comprehensive data sheet, which manufacturers can use for the fabrication of transformers and inductors. The MPE also generates the inductor and transformer PSpice simulation models. Included with the MPE is a database of commercially available magnetic parts such as wire types, insulation material, bobbins, and magnetic cores. One can add to this database by creating one's own magnetic parts. The design cycle consists of a series of design steps, which are numbered as one progresses through the design. The design steps for a DC-DC converter using the flyback topology is presented in this chapter as an example. The MPE is started from the PSpice Accessories menu.
