Modelación de un cañón electromagnético mediante ATP-EMTP y ATPDraw

Abstract

This work presents a model of an electromagnetic cannon developed using the ATP-EMTP tool and its graphical environment, ATPDraw. The design is based on multiple stages of circular coils through which a cylindrical metallic armature moves. Utilizing the VBR technique, each coil is transformed into a dynamic equivalent consisting of a resistance, an inductance, and a source of electromotive force. These parameters are determined instantaneously based on the dynamics of the mechanical system. The coils are activated by initially charged capacitors and are connected via thyristors, which are triggered at specific moments determined by the position of the armature. The validity of the model is verified through experimental results reported in the literature, ensuring the accuracy and effectiveness of the proposed approach. This study not only contributes to the understanding of electromagnetic cannons but also establishes a foundation for future research and applications in this field.
