Modeling of New Single-Phase High Voltage Power Supply for Industrial Microwave Generators for N=2 Magnetrons

In this paper, we propose to study the modeling and the simulation, using the EMTP code, of the operation in nominal mode of a new high voltage power device, based on the same use principle of an only transformer with shunts, but this time for several magnetrons. This modeling can lead to the determination of the construction parameters of the new transformer, to ensure the correct operation in nominal mode of the new power supply, while respecting the control criterion of the current in each magnetron. The knowledge of these parameters (size of the magnetic circuit, the magnetic quality, the air gap, the size of the shunt and the number of turns, etc .....), determines the cost of the dimensioned transformer for its realization. In the following, we will treat all possible states for operation of this new power supply with two magnetrons (Power supply for two magnetrons: case of two magnetrons in service, case of one magnetron in service and one magnetron in failure, case of tow magnetrons in failure). This provides relative to the current device gains of space, volume, cost of implementation and maintenance.DOI:http://dx.doi.org/10.11591/ijece.v4i2.568

Modeling Under MATLAB by ANFIS of Three-Phase Tetrahedral Transformer Using in Microwave Generator for Three Magnetrons Per Phase

This work deals with the modeling of a new three-phase tetrahedral transformer of HV power supply, which feeds three magnetrons per phase. The design of this new power supply is composed of three single-phase with magnetic shunt transformers coupling in star; each one is size to feed voltage-doubling cells, thereby feeds a magnetron. In order to validate the functionality of this power supply, we simulate it under Matlab-Simulink environment. Thus, we modeled nonlinear inductance using a new approach of neuro-fuzzy (ANFIS); this method based on the interpolation of the curve B(H) of ferromagnetic material, the results obtained gives forms of both voltages and currents, which shows that they are in accordance with those of experimental tests, respecting the conditions recommended by the magnetron manufacture
