Abstract: The power converter loss in switched reluctance motor system is one of the main reasons affecting system reliability.
Therefore a practical electrothermal model is established to calculate the losses based on lookup tables of motor flux linkage and
device switching losses. It utilises the thermal RC network to estimate the junction temperature rise. Then, the influences of
system factors on the losses are investigated with different control strategies. At last, the device junction temperature rises are
present at different rotor speed, and verified by experiments.
Conclusion
This paper proposed the converter electrothermal model for
SRM system to calculate the device losses and junction
temperature rises. The model is validated with the
experimental results. The factors and their influences on the
losses are analysed with and without PWM signals.
Moreover, the device junction temperatures and losses are
independent of rotor speed regardless of friction. At last,
the proposed model can also adapt to other control
strategies for SRM system.
