<p>The present invention relates to a driving apparatus of a switched reluctance motor, wherein a first, second and third delayer (24-1, 24-2, 24-3) delay for a predetermined time A phase, B phase and C phase rotor position signals output from A phase, B phase and C phase position sensors (22-1, 22-2, 22-3) to thereby output gate signals of lower switching elements (Q2, Q4, Q6) of switched reluctance motor driving circuit respectively, so that the lower switching elements (Q2, Q4, Q6) is turned off later by a predetermined time than upper switching elements (Q1, Q3, Q5), thereby offsetting and reducing radial force generated when the upper switching elements (Q1, Q3, Q5) and the lower switching elements (Q2, Q4, Q6) are turned off for decrease of noise at the switched reluctance motor.</p> |
