| Abstract |
A new term in switched reluctance motor (SRM) drives, namely stored energy variation factor (SEVF), is presented in this study, which is defined as the ratio of stored energy variation to total input energy. SEVF is similar to power factor (PF) in switched reluctance motor drive. The analytical expression of SEVF is derived when switched reluctance motor drive runs under voltage PWM operation. In addition, the computation of SEVF under single-pulse operation is described. The computations and the experiments show that SEVF can indicate not only DC energy changes, but also changes of power factor under both PWM and single-pulse operation. SEVF can provide an insight into the DC energy conversion in switched reluctance motor drives. |
