Switched Reluctance Motors (SRM) are known as uncomplicated structure machines, have some characteristics which make them remarkable for high speed low voltage applications. Due to have full utilization of SRNI performance, attain to efficient drive circuit for this kind of motors is desirable. In this paper, a new class of modified C-dump drivers with PI Capacitor Bridge for switched reluctance motors is proposed. This new drive circuits take the advantage of having faster rate of energy discharge from each phase windings and an energy recovery circuit. Faster rate of fall for phase current permits the motor to operate at higher speed and also prevents the motor to work at saturation mode. This feature improves motors torque profile because of phase's demagnetization. To have better consideration about this new class of C-dump drive circuit, simulation analysis for proposed PI Capacitor Bridge C-Dump drive circuit is carried out.

A ZVS-Resonant Bifilar Drive Circuit for SRM with a reduction in Stress Voltage of Switches Ebrahimi, Seyyedmilad; Najmi, Vahid; Ebrahimi, Seyedyaser; Oraee, Hashem (2011-09-10) Switched Reluctance Motors (SRMs) are widely used in high-speed and low voltage applications because of their attractive features such as robustness and simplicity. No winding on the rotor of this type of motors allows reaching high speed which is desired for many applications. Drive circuits of SRNIs also play an important role in their performance and operation. In this paper, a new bifilar drive circuit for this type of motors has been proposed. This novel configuration has been tested and investigated b...
An analytical approach for determination of optimal stator/rotor saliency number of a swıtched reluctance motor Kılınç, Cem Erkan; Bostancı, Emine; Department of Electrical and Electronics Engineering (2020) The purpose of this study is to seek the optimal stator and rotor saliency number of a switched reluctance motor (SRM) for hybrid electrical vehicle (HEV) applications. For this purpose, first a previously developed SRM analysis software is investigated to identify possible errors in implementation of both the theory and the coding. Performance prediction method is based on the use of normalized force and permeance data produced via numerical field solution, and a polynomial based interpolation is introduce...
A Novel Noise Reduction Technology for Switched Reluctance Motors Bizkevelci, Erdal; Özlü Ertan, Hatice Gülçin; Leblebicioğlu, Mehmet Kemal (2008-07-24) The conditions are sought at which an SIR motor can be operated with highest efficiency, while producing a desired torque output at low shaft torque ripple. The investigation is based on the simulation software that uses measured flux-linkage (V, 0, 1) and static torque (T, 0, 1) characteristics of a given motor. The variation of the shaft torque, torque ripple and efficiency of the motor Is investigated, while the control variables "advance angle" and "conduction angle" are swept over their range with a co...
Comparison of Inverter Topologies Suited for Integrated Modular Motor Drive Applications Ugur, Mesut; Sarac, Hakan; Keysan, Ozan (2018-08-30) In this paper, various inverter topologies are compared for integrated modular motor drive (IMMD) applications. Two-level voltage source inverter (2L-VSI), three level voltage source inverter (3L-VSI) and series/parallel combinations of these topologies with system level modularity are compared in terms of voltage and current harmonic spectrum, passive component sizes and motor drive efficiency. New generation wide band-gap GaN power semiconductor devices are utilized in modular topologies and they are comp...
Mechanical and Thermal Design of an Optimized PCB Motor for an Integrated Motor Drive System with GaNFETs Tokgöz, Furkan; Gulsuna, Ozgur; Karakaya, Furkan; Çakal, Gökhan; Keysan, Ozan (2022-01-01) PCB motors are a viable alternative to commercial electric motors as they are easy to mass-produce and have low manufacturing costs. Moreover, integrated motor drives have gained popularity thanks to their high power density and ease of installation. However, the mechanical and thermal aspects are challenging due to reduced volume. In this paper, a GaNFET switched integrated motor drive axial-flux permanent magnet synchronous machine with a printed circuit board (PCB) stator is designed. The machine is opti...
