Design and Modeling of New Configuration of Three Phase Transformer For High Voltage Operation Using in Microwave Industrial

摘要

The present paper aims to validate the design of new configuration for a high voltage transformer with magnetic shunts; this new type was based on coupling the primary of phase 1 with the primary of phase 2, and the secondary of phase 2 with the primary of phase 3 (sp-ps-ps), The aim of this study is to compare this new design with the previous and make the advantage of each one, this system is composed of a new simple phase leakage flux transformer supplying a cell, composed of a capacitor and a diode, which multiplies the voltage and stabilizes the current. A π quadruple model of this transformer is developed taking account the saturation phenomena and the stabilization process of each magnetron current. Each inductance of the model is characterized by a nonlinear relation between flux and current, that we obtain directly from data transformer.
