  • Switched Reluctance Motor (SRM) has a characteristic that the inductance changes very nonlinearly depending on the magnitude of the current and the relative position of the rotor and stator, and the torque is generated In consideration of these problems, many studies have been conducted on a topology for driving that can improve efficiency and performance in an existing asymmetric bridge converter in order to simplify the circuit and economic efficiency. Therefore, in this paper, we want to check the performance by comparing and analyzing each converter used by applying it as a topology for SRM driving. The driving converters applied to the comparison and analysis are Conventional C-dump, Modified C-dump, Energy efficient C-dump, Resonant C-dump converter with C-dump converter type structure and the most widely used asymmetric bridge converter and 6-Switch inverter that used for general motors.

  • Recently, SRMs are used in automobiles for power assistant steering, accessory motion control and traction drives. Especially in the motion control and traction drives, safety and efficiency are of paramount importance. The paper describes the essential elements faced in designing and constructing driving circuits for a switched reluctance motor for automobiles. An important factor in the selection of a motor and a drive for industrial application is the cost. The switched reluctance motor(SRM) is a simple, low-cost, and robust motor suitable for variable-speed as well as servo-type applications. With relatively simple converter and control requirements, the SRM is gaining an increasing attention in the drive industry. This paper presents a modified C-dump converter for Switched Reluctance Motor (SRM) machine application in the cooling system of automobiles. The experiments are performed to verify the capability of applicate control method on 6/4 salient type SRM.

  • In order to obtain the maximum characteristics of motors such as torque and efficiency, all motors basically use universal inverters designed for each motor's characteristics. However, if you look at the recent research results, you can see cases of SRM(Switched Reluctance Motor) driving studies using 6-switch inverters, which are BLDC(Brushless DC Motor) universal inverters, and research cases of driving 3-phase BLDC motors using 4-switch inverters. Therefore, it is possible to search for research methods by approaching various methods of driving and control that can drive each motor apart from the existing universal inverter. In line with this research trend, in this paper, a C-dump type converter, which is an SRM drive converter, was applied as a drive driver for a BLDC motor, and its characteristics and possibilities were studied.
