Switched reluctance generator phase current theoretical analysis

Decreases), the electrical energy storage for a long time, the rms current increases. At this time because of the small,[link widoczny dla zalogowanych], small inductor current rise time long. (2) off the main switch peak current impact angle ‰ in the different sections of its continued shutdown will result in increased flow of current curves of different shapes, addition, the turn-off angle ‰ increases, the supply time increases, the current RMS big. (3) control angle in certain conditions, the current effective value inversely proportional to the speed and low speed, the angle corresponding to the same conduction-time long, long time storage, so current is large. This analysis did not account winding mutual inductance, mutual inductance should be said that existence is objective, but because of this the same motor when power is applied in two (one phase excitation, a phase continuous current), which cross the magnetic circuit is not close coupling, so the mutual inductance and mutual inductance is generally not great. 4 Comparison of test results and the recent trial of a switched reluctance generator, three-phase 6 / 4 structure, the main technical indicators and main dimensions are as follows: rated power 3kW, rated speed, rated output voltage 270Vm 9OOOr/rain, efficiency 0.75 stator large diameter 130ram,[link widoczny dla zalogowanych], stator and rotor core length l10ram, gap 0.2mm, center height 90rmm. 5 Conclusion switched reluctance generator is generating a new field, for this generator, its motor phase current resolution is key to the analysis, this article from the basic equations of switched reluctance generator set, a detailed analysis of its cycle phase current waveform for further analysis and study of the motor provides a theoretical basis.
