A Control Method with Ring Structure for Switched Reluctance Motor

It is known that in order to drive a switched reluctance motor (SRM), the power converter is required, which makes it different from other common type of motors such as brushless direct current motor (BLDC). As a result, the cost of the control system for SRM is higher than the conventional inverter structure of control system for BLDC. A new control strategy for SRM is proposed in this paper, with an extra DC power supply, SRM can be driven by a general inverter without changing the structure of the motor itself, the cost for driving SRM can be reduced drastically. The new control method is also tested with simulation and validation, which prove that the new method can work in the practical application.
