Abstract

This article deals with the optimization of a three-phase tetrahedral-type high voltage transformer, sized to supply three voltage-doubling cells and three magnetrons per phase. The optimization method used is based on an algorithm implemented in Matlab/Simulink to study the influence of transformer geometrical parameters on the electrical operation of the power supply. This study will allow to find reduced volume of transformer respecting the current constraints imposed by the magnetrons manufacturer. The choice of optimal solution is done by calculation of magnetrons powers in order to respect the nominal operation.

Highlights

  • In the development study of power supplies for microwave applications, we always seek to find more powerful and optimal solutions in terms of installation space, cost of manufacture and maintenance

  • We study the influence of each geometrical parameter of the transformer on the operation of the power supply

  • This model will allow us to study with respect to the reference transformer case the sensitivity of each geometrical parameter to the nominal operation of the power supply [11-13]

Summary

INTRODUCTION

In the development study of power supplies for microwave applications, we always seek to find more powerful and optimal solutions in terms of installation space, cost of manufacture and maintenance. In this context, this work defines a method to optimize the three-phase HV transformer used in this kind of power supplies with nine magnetrons (three for each phase). This study will allow us to define the optimized algorithm based on the simultaneous variation of these parameters This leads to various solutions that respect the criteria recommended by the magnetron manufacturer.
