The method of controlling a converter of a switched reluctance machine includes clocking a power switch with a frequency that depends on the width of the hysteresis band. The hysteresis width is varied according to reluctance machine speed, especially so that a difference between maximum and minimum values with which the current is switched on and off either increases with decreasing speed, decreases with increasing load, or both. The changing of the hysteresis width occurs so that a difference between maximum and minimum threshold values either increases with decreasing speed, decreases with increasing load, or both. The width of the hysteresis band preferably varies linearly with speed, load and/or current, especially so that the width of the hysteresis band varies linearly so that the clocking frequency is maintained substantially constant. Also targeted changes in the width of the hysteresis band are made to move the clocking frequency from near noise-critical resonance frequencies.
