Abstract
This paper proposes the SRM drive system based on DC-link current, from which the phase currents can be estimated in accuracy and also they can be used in driving SRM instead of the three-phase currents. In additional, the detecting circuit for DC-link current is also proposed for increasing the resolution and decreasing the off-set. Comparing to the general drive system based on the phase current, it is verified through the experiment that the proposed SRM drive system has the good performance in steady-state responses of the speed control. Using the DC-link current, all of the 3-phase currents can be easily estimated in driving the SRM.
