KEYWORDS As experience shows while studying the magnetic field, it can be assumed that the machine's magnetic field is plane-parallel. Mathematical simulation, synchronous machine, magnetic field. It is appropriate to substitute the electromagnetic field equations system with one equation which depends on the magnetic vector potential, having only one(More)
In many spheres of human activities devices that work on increased frequency current are widely applied. 50 Hz current can be converted into increased frequency (100-400 Hz) current using synchronous reactive converters, which are based on exude and usage of higher harmonics. The goal of this paper is to determine which circumstances must be taken into(More)
