obwód magnetyczny - Opis:
- It was presented how to design three column substitute diagram of the main magnetic circuit using the impedance matrix of the autotransformer obtained by FEM 3D methods [1, 6, 7]. Relation between main inductances of the magnetic circuit and angular frequency caused by eddy currents in the autotransformer plates was modeled by additional windings on columns short-circuited by admittances. These admittances were synthesized by Cauer ladder schemes. Magnetic saturation of the columns in the substitute diagram should be considered using traditional methods. The substitute diagram presented in this article should be complemented by ladder circuits, which synthesize zero component inductance and leakage inductance [8] of the transformer. Then the diagram can be used for fast calculations of the transient states in clean power multipulse rectifiers circuits. This way of calculations represents proper conditions of the diodes commutation and allows for studying of the circuits higher harmonics.
