indukcyjność rozproszenia - Opis:
- Commutation processes in power electronic converters are significantly dependent on the leakage inductances of the transformer. The calculations of the leakage inductance matrix where preformed with use of the finite element method (3D). The eddy current losses were taken into consideration. The mono harmonic calculations for different frequencies where performed. The dependence of magnetical inductance main, component zero and leakage were showed from frequency. This caused rotational currents in the core of the autotransformer and in the conductors of windings is. The way of the fusion of these inductances was introduced ladder arrangements. Adaptation of these inductances to the calculations of courses transitory converters district methods was the aim. The article presents ladder circuits, which synthesize zero component inductance and leakage inductance of the transformer. They are also used to complement [8] (remove imperfection) substitute diagram of the main magnetic circuit of the transformer. Including the substitute diagram they can be used for fast calculations of the transient states in clean power multi-pulse rectifiers circuits. This way of calculations represents proper conditions of the diodes commutation and allows for studying of the circuits higher harmonics.
