Operating Switched Reluctance Machine in Low Inductance to Reduce Current Chopping Frequency

Switched Reluctance Machine (SRM) operates in a low-increased inductance in a motoring mode and high-deecreasing inductance in a generating mode. If the machine is switched accordingly, the corresponding slope of current varies with the increase and decrease of the inductance profile of the machine. The switching frequncy of SRM greatly varies in accordance to consequence of current chopping if the machine oprates in that mode. This paper addresses a welldefined and simple methodology of selecting an optimal optimal switch on angle within a low inductance region to reduce the switching frequency of SRM. Hence switching power loss can also be reduced which minmises the converter losses of SRM. The simulations are carried out in MATLAB/Simulink environment.
