Mathematical models of non-sinusoidal power supply of a three-phase transverse field MHD inductor

The article presents an approach to the development of mathematical models non-sinusoidal and dual-frequency power supply for a linear induction MHD machine metallurgical purposes. issues construction numerical modeling modes three-phase inductor liquid aluminum stirrer are considered. Reduction losses is ensured by use toothless design inductor. absence steel teeth reduces saturation magnetic circuit current distortion. It proposed parametric model under furnace in ANSYS environment clarify complex. To take into account mutual induction, using controlled sources, was built, calculation carried out. characteristics instantaneous currents voltages obtained when powered from source with close frequencies, pronounced beats. shown that presence inductance redistributes delta windings, which must be taken developing machines. sources periodic system. analysis out main types modulated voltage system shown.
