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 by PSIM software. Results show that the new bifilar drive circuit highly reduces the voltage stresses on semiconductor switches, and also considerably reduces the switching losses which are very important in low voltage applications. Finally, a comparison between this new drive circuit and some other common configurations is presented.

New Modified C-dump Drivers With PI Capacitor Bridge for Switched Reluctance Motor Najmi, V.; Siadatan, A.; Afjei, E.; Afjei, M. S. (2011-09-10) 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 eac...
Active clamped ZVS forward converter with soft-switched synchronous rectifier for maximum efficiency operation Acik, A; Cadirci, I (1998-05-22) An active-clamped, zero-voltage switched forward converter equipped with a soft-switched synchronous rectifier is designed and implemented for some low output voltage applications where maximized efficiency is of utmost importance. The converter efficiency is maximized due to soft-switching of the main, active clamp and the synchronous rectifier MOSFET switches. Experimental results are presented for a converter with a de input voltage of 48V, an output voltage of 5V and a de electronic load up to 10A. The ...
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...
Performance and thermal reliability comparisons of 2-level and 3-level NPC voltage source inverters for electric vehicle drive applications Madan, Alican; Bostancı, Emine; Department of Electrical and Electronics Engineering (2019) Two-level and multilevel inverters are widely used in electric vehicle drive applications with different switching techniques. Selection of the topology and the switching technique for electric vehicle drives are getting more important with the trend of designing more compact and more efﬁcient drive circuitry. Reliability of semiconductors in power electronics are under investigation in recent years as well. In this thesis, a multidimensional comparison of two common topologies for a 120 kW electric vehicle...
Development of X-Band Transceiver MMIC's Using GaN Technology Memioglu, Onur; Kazan, Oguz; Turan, Isinsu; Karakuzulu, Alper; Gundel, Adnan; Kocer, Fatih; Aydın Çivi, Hatice Özlem (2019-01-01) This paper describes X-Band power amplifier (PA), low noise amplifier (LNA) and switches that can be used in transmit/ receive modules which are developed with GaN technology. For Transmit chain two 25 W high power amplifiers that are tuned between 8-10 GHz and 10-12 GHz bands are designed. A low noise amplifier with 2 W survivability and less than 2dB noise figure is designed for receive chain. Furthermore, an RF switch that is capable of withstanding 25 W RF power is developed for the selection of transmi...
