Abstract

Recent publications have shown that the adverse acoustic behavior of automotive-size switched reluctance machines can be tackled by aid of Direct Instantaneous Force Control. The former work mainly focused on the functionality regarding acoustics. This paper, however, compares the drive losses between standard Hysteresis Current Control and Direct Instantaneous Force Control. Iron loss, copper loss and losses of the inverter were investigated by simulation. It turned out that iron loss decreases when applying Direct Instantaneous Force Control. Ohmic losses inevitably increase, though. Therefore, it depends on the load-cycle of the vehicle whether Direct Instantaneous Force Control or standard control is preferable.
