Abstract
Disclosed is a single-phase switched reluctance motor (SRM) driving apparatus and method which enables a high-speed and high-efficiency SRM and can minimize the switching frequency of elements for driving the SRM. The SRM driving apparatus includes a smoothing circuit section for smoothing an input power supply, a motor driving section for receiving a voltage smoothed by the smoothing circuit section and supplying the voltage to a motor in accordance with a control signal, a plurality of sensors for sensing a rotating speed and a phase of the motor, and a microcomputer for receiving one selected among signals sensed by the plurality of sensors and outputting the control signal for controlling the motor driving section.
