Abstract

This original work treats the feasibility study of a new HV power supply with a three-phase character, supplying a magnetron 800 Watts-2450 MHz per phase, for industrial microwave generators from the modeling with the EMTP code of a single-phase HV power supply for one magnetron. The exploitation of the modeling, with EMTP code, of the power system for one magnetron is to use, essentially, the developed model of its transformer, which is a π quadruple, consisting of saturable inductances able to translate the non-linear phenomena of saturation, while guaranteeing the stabilization process of the magnetron current. Using the new power supply device with a three-phase character and the EMTP code, the feasibility study, in nominal mode, of the three-phase power supply was performed satisfactory. The analysis of the results obtained helped to confirm the possibility of functioning of this new system without interaction between magnetrons, which provides, relative to the current device, gains of size, volume, cost of implementation and maintenance and makes this new system more economical, while guaranteeing the regulation process of the current in each magnetron.DOI:http://dx.doi.org/10.11591/ijece.v3i2.2409

Abstract

This paper treats the modelisation of a new three phase character high voltage supply (HV) for industrial microwave generators with N=2 magnetrons per phase. This alimentation is based on the presentation of an equivalent p circuit model of a newly dimensioned high voltage transformer. Each phase of the three phase system supplies two parallel cell voltage doublers and current stabilizer. Each of these cells in turn supplies one magnetron 800Watts / 2.45GHz. This power supply is a star connection of three identical models of the single-phase power for N=2 magnetrons. The simulation under EMTP (Electro Magnetic Transients Program) in nominal conditions allows concluding that theoretical results are adjacent to the experimental measurements. Furthermore, a failure study of six magnetron of the microwave generator is also processed. The results permit to observe that the interaction between magnetrons dosn’t influence the nominal operation of the system.

Abstract

This work deals with the energetic validation of a new optimized high voltage power supply for micro-waves generators with N=2 magnetrons that are used as an energy source in industrial applications. In this article, we will apply an optimization strategy that aims at improving the nominal functioning of the optimized power supply with N=2 magnetrons. Unlike research work already done an this topic, this article treats the correct energetic functioning of the two magnetrons. An equivalent scheme in π of the transformer model is presented with the geometrical parameters taken as reference. This model has been tested with the help of the simulation software Matlab-Simulink close to nominal operation. The theorical results compared to the experimental measures are in good conformity. Following that, we will validate the functioning of the new optimized power supply by calculating the average power and then comparing it with that which was found for the power supply with geometricals parameters taken as reference.DOI:http://dx.doi.org/10.11591/ijece.v2i5.1588

Abstract

This original work treats the modeling of a new type of HV power supply with several magnetrons (treated case   N=3 magnetrons).The design of this new power supply uses a new single-phase high voltage transformer with magnetic shunts supplying three doublers voltage cells, each one composed of a capacitor and a diode. Each cell supplies in its turn one magnetron. The π equivalent model of the transformer is developed taking account the saturation phenomena and the stabilization process of each magnetron current. The model of the transformer is based on the determination of the analytical expressions of the non linear inductances that can be stored from the fitting of the magnetization curve B (H) of material used. The resulting model will be implemented under Matlab-Simulink code. The simulation results are in good agreement with the experimental measurement for one magnetron, thus provides, relative to the current device, gainsof volume, weight and cost of all power supply with respecting the conditions recommended by the constructor of magnetron current: Ipeak<1.2 A, Imean≈ 300 mA.DOI:http://dx.doi.org/10.11591/ijece.v3i2.2238
