Maximum Current Tracking in Switched Reluctance Motor Converters
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 5, Issue 11
Abstract
In this paper, two types of converters are used in order to drive a 12 by 8 and 6 by 4 three-phase Switched Reluctance Motor (SRM). One of them is a Two-Switch per Phase (TSP) converter which has two transistor and two schottky diodes in each phase. The other on is N Switches in N Phases (NSNP) converter in which one switch is used in each phase. The SRMs are then tested in laboratory with the both converters and the current-speed curves of them are obtained for different values of speed. The current-speed curves are then compared. Because of using schottky diodes in TSP converter, the energy stored in the phase is turned back to the voltage supply during switching which increases the efficiency of the converter. But in NSNP converter, the stored energy is not able to turn back to the voltage supply and loses in the phase as ohmic losses which decreases the efficiency of the motor and increases the motor current consumption.
