Abstract
Disclosed herein are a switching control apparatus for a two phase switch reluctance motor and a control method using the same. The switching control apparatus includes a rectifier; and an active converter including a pair of common switches, a pair of first phase switches, a pair of serially connected second phase switches, a plurality of current feedback diodes each connected to the switches, and a pair of drivers controlling the switches and operated as operation modes 1 to 3 to provide the commercial power provided from the rectifier to the two phase SRM and drive the two phase SRMs.

A switching control apparatus for a two phase switch reluctance motor, comprising:
- a rectifier rectifying commercial power;
- and
- an active converter including a pair of common switches having two phase windings of two phase SRMs commonly connected to a contact therebetween, a pair of serially connected first phase switches bridge-connected to the pair of common switches at any one of the two phase windings, a pair of serially connected second phase switches bridge-connected to the pair of common switches at the other one of the two phase windings, a plurality of current feedback diodes each connected to the switches, and a pair of drivers controlling the switches and operated as operation modes 1 to 3 to provide the commercial power provided from the rectifier to the two phase SRM and drive the two phase SRMs.
A switching control method for a two phase switch reluctance motor, comprising:
- (A) controlling, by a microprocessor, an active converter including a plurality of switches bridge-connected at each phase winding of a two phase SRM, a plurality of current feedback diodes each connected to the switches, and a pair of driver splitting and controlling the plurality of switches, to excite any one of the phase windings and remove residual current;
- and
- (B) controlling, by the microprocessor, the active converter to excite the other one phase winding and remove the residual current.
