Control of an inductive load

摘要: A switched reluctance machine controller derives an error signal from the difference between a current reference and phase winding current. The error signal is applied to pair of hysteresis circuits which define adjacent bands above below the reference magnitude bands may vary as function current reference. The outputs are received by control logic which permits be the phase when hysteresis bands, removes the current allows freewheel is between upper lower limits. power device used for freewheeling alternates an upper power device power device.
