A switching control apparatus of a two-phase switched reluctance motor, comprising:

a rectifying unit rectifying commercial power;
and
an active converter including a pair of common switches having two phase windings of the two-phase SRM commonly connected to a contact therebetween, a first phase switch and a first current feedback diode bridge-connected to the pair of common switches at any one of the two phase windings and connected in series with each other, a second phase switch and a second current feedback diode bridged-connected to the pair of common switches at the other of the two phase windings and connected in series with each other, and a plurality of current feedback diodes each connected to the switches and operated in operation modes 1 to 3 to supply the power provided from the rectifying unit to the two-phase SRM, thereby driving the two-phase SMR.

A switching control method of a two-phase switched reluctance motor, comprising:

(A) controlling, in a microprocessor, an active converter including a pair of common switches having two phase windings of the two-phase SRM commonly connected to a contact therebetween, two groups of phase switches and current feedback diodes each bridge-connected to the pair of common switches at corresponding phase windings and connected in series with each other, and a plurality of current feedback diodes to excite any one of the phase windings and then remove residual current;
and
(B) controlling, in the microprocessor, the active converter to excite the other of the phase windings and then remove residual current.
