Failures’ Study of a New Character Three - Phase High Voltage Supply for industrial Microwave Generators with one magnetrons per Phase

“…shows the schematic diagram of the new three-phase high voltage power supply for one magnetron per phase [1] [2][3] [4], which corresponds to a star connection of three equivalent electrical models of the single-phase power supply for one magnetron. It is composed of an equivalent electrical model of its corresponding single-phase HV transformer with magnetic leakage flux [5] [6] [7] [8], which supplies one voltage doubler and current stabilizer circuit that supplies one magnetron. In the first part of this article, we present a global equivalent circuit diagram of this power supply.…”

New Simulation Method of New HV Power Supply for Industrial Microwave Generators with N=2 Magnetrons

“…The modeling already developed [1][2][3][4][5][6][7][8][9][10][11] of a single-phase HV power supply for one magnetron 800 Watts-2450 MHz (Figure 2) is to model essentially the special HV transformer with magnetic leakage which ensures the stabilization of the means anodic current in the magnetron. The equivalent model of the selected transformer will be integrated into the overall scheme of the power supply to be adapted to the modeling of the whole system with MatlabSimulink.…”

“…To perform this modeling [1], [3], [4] we have sought to integrate the model of the transformer in the power circuit from the source to the magnetron (Figure 3), where we represented the microwave tube by its equivalent circuit deduced from its electrical characteristic that is formally similar to that of a diode with dynamic resistance of 350Ohms and threshold voltage E3800 volts.…”

“…This paper discusses a new simulation method modeling a new high-voltage power supply for N=2 magnetrons 800Watts-2450 MHz of the figure 1, used as a source of energy microwave. The design of this new power supply uses a HV transformer with magnetic leakage supplying two cell voltage doublers and stabilizers of current [1][2][3][4][5][6][7][8][9][10][11][12][13]. The transformer with magnetic shunts ensures the stabilization of average anode current in each magnetron, thanks to the saturation of his magnetic circuit.…”

Comparative Studies of Electrical Functioning of Magnetron Power Supply for One Magnetron

“…In the first part, we will establish the study of energy balance for power supply powering one magnetron, but before we are forced to present in this paper, the equivalent model [1], [2], [3], [4], [5], [6] retained for the transformer which will be integrated into the overall scheme of the power supply that will be adapted at the modeling of the entire system using a powerful tool for numerical calculation of electrical circuits such as Matlab-Simulink. The first experimental setup discussed in this article will allow to find the different waves of currents and voltage that exist in the whole system of power supply.…”
