The advent of inexpensive high power switching devices revived the interest in switched reluctance motor(hereafter referred to as SRM) drives. In the late 60's, the potential of SRM for traction application attracted researchers. Since then the progress in research of the SRM drive has been phenomenal. In this paper, a review of the basic principle of operation of the SRM, currently available converter topologies, the controller requirements and some design considerations are included.

The new converter topology using full bridge inverter for the switched reluctance motor drives is proposed. The proposed SRM drives are supplied by the pulse voltage source, while the conventional drives are supplied by dc voltage source. Proposed converter maintains the characteristics of asymmetric bridge converter and has advanced characteristics.

Switched reluctance motor(SRM) has the advantages of simple structure, low rotor inertia, and high poer rate per unit volume. However, position sensor isessential in SRM in order to synchronize the phase excitation to the rotor position. The position sensors increase the cost of drive system, and tend to reduce system reliability. This paper investigtes the speed control of sensorless SRM. The proposed system consists of position detection circuit, dwell angle controller, digital logic commutator, PI speed controller and 4-phase inverter. The performances in the proposed system are verified through the experiment.

In this paper, an auto-tuning method for fuzzy controller based on the neural network is presented. The backpropagated error of neural emulator offers the path which reforms the fuzzy controller's membership functions and fuzzy rule, and used for speed control of switched reluctance motor. The experiments are performed to verify the capability of proposed control method on 6/4 salient type SRM. The results show that fuzzy-neural controller is suitable for wide speed range.

The torque of SRM is developed by phase currents and inductance variation. Phase currents and inductance variation. Phase current is often the controlled variable in electrical motor drives, so it seems natural to use closed loop current controllers. However, the highly nonlinear nature of switched reluctance motors makes optimisation of closed loop current controlled difficult because of saturation effect in magnetic circuit. Therefore, torque generation region is nonlinearly varied according to phase current and rotor position. This paper describes the torque control scheme with neural network that can control varied with load torque. The torque control is simulated by PSIM.

본 논문은 Switched Reluctance Motor(SRM)의 보다 정확한 제어를 위한 인덕턴스 측정에 대해 설명한다. 기존의 인덕턴스 측정방법에는 등가회로를 이용하여 측정하는 방법과 시정수를 이용하여 측정하는 방법이 사용되어왔고 본 논문에서는 기존의 인덕턴스 측정방법과 자동화된 전압적분법을 이용하여 인덕턴스를 측정하였고 실제 측정 데이터 및 유한요소해석(FEA : Finite Element Analysis) 데이터와의 비교를 통하여 타당성을 입증하였다.

The recent flurry of activities and interest in Switched Reluctance Motor(SRM) has focused attention on various issues associated with implementing the SRM in the mass commertial Market. One such issue is the noise generated by radial force. In this paper, we proposed the circuit to reduce the noise of SRM using LC Resonant characteristic. The usefulness of proposed circuit is verified by experimental result.

The new converter topology using half bridge inverter for the switched reluctance motor drives is proposed. The proposed SRM drives are supplied by the pulse voltage source, while the conventional drives are supplied by de voltage source. Proposed converter does not lose the characteristics of classic converter though the total no. of power switches are reduced.
