Contribution to development of a new transformer with a single magnetic shunt for industrial microwave generators

Abstract

The main objective of this work is to treat the different proposed geometrical configurations of a high voltage transformer with a single magnetic shunt instead of that of dual magnetic shunts for industrial microwave generators power supply. This article deals with development of the single-phase high-voltage power supply based on a new model of equivalent column-type magnetic circuit for a special transformer with a single magnetic shunt, which has a special structure and wide applications. This work shows a detailed design and implementation procedure, including the design of the power supply. The sizing and the feasibility study of the equivalent transformer is covered in this articleThe experimental results are provided in order to validate the model proposed. The electric diagram obtained of this model is tested in nominal mode, using the software EMTP (Electro-Magnetic Transients Program). The electrical operation simulation was consistent with the experiments in the case of conventional power supply.

3D Electromagnetic and Thermal Behaviour Analysis of Magnetic Flux Leakage Transformers Using Finite Element Method

“…Modeling the magnetic behavior of a magnetic core can be accomplished by utilizing either the magnetic hysteresis loop or the B-H curve. The B-H curve characterizes the correlation between the magnetic flux density (B) and magnetic field strength (H) in a material, and can be obtained through experimental measurements of the material's response to varying magnetic fields [1], [14], [15].
