New electrical model, simulation and optimization of a high voltage power supply for industrial microwave generators with two magnetrons, 1600 watts at 2.45GHz

Abstract

The purpose of this paper is to develop a new high voltage power supply for N=2 magnetrons, 800 Watts at 2450 MHz each; using a high voltage transformer with magnetic shunts. We present a new equivalent electrical circuit of this transformer which allowed, through its integration into the global electrical diagram of the new power supply, to model the entire high voltage power supply using numerical computation software EMTP dedicated to the transitional regimes. Then, a study of the influence of each geometrical parameter of the special HV transformer with magnétic shunts will guide us studying the optimization's strategy of this high voltage power supply for industrial microwave generators. This study allows achieving an important volume gains, congestion and weight, then consequently reducing the different costs of this high voltage power supply.
