ABSTRACT:
Disclosed is a current controlling apparatus of a switched reluctance motor (SRM) having an inverter unit for variably switching the excitation state of each phase of the polyphase stator: generates a current controlling signal so that a current error between a current commanded by a current command unit and a current which is actually applied to the SRM can be compensated; and performs a pulse width modulation after receiving the current controlling signal and then supplies to the inverter unit, thereby enhancing efficiently the operating characteristic of the SRM by minimizing the current error. In other words, the current control apparatus in the SRM which searches for a current error by comparing a current controlling signal commanded by a current command unit with a current actually applied to the SRM and then operates the SRM by a current adjacent to the command current by compensating a current value corresponding to the compared current error. As a result, it is possible to reduce a noise caused by a torque ripple when rotating the motor and enhancing the efficiency of the motor.
