PV-Battery Powered Direct Torque Controlled Switched Reluctance Motor Drive

Abstract

Categorized as one of the renewable energies, PhotoVoltaic system has a great potential compared to its counterparts of renewable energies. This paper deals with the design of a Photovoltaic (PV)-Battery fed Switched Reluctance Motor(SRM). The system mainly composed of a PV module, boost converter, rechargeable battery, bidirectional converter, asymmetric bridge converter, SRM and system controllers. The main problems of SRM are high torque ripple, acoustic noise and vibration problems. In order to reduce these problems, a new direct torque control of 3.5 kW 8/6 SRM is proposed, which is simple and can be implemented with low cost processor. It can be seen from the simulation results that this scheme has well regulated the torque output of the motor with in hysteresis band. The proposed system assures its suitability for solar applications like solar vehicles, solar water pumping system and floor mills in hilly and isolated areas.

Efficiency improvement and torque ripple minimisation of four‐phase switched reluctance motor drive using new direct torque control strategy

“…The dividing head is used to lock the rotor at each position against the torque produced. The measured voltages and currents are further processed into a simulation platform to calculate flux linkages using (7). The motor parameters and the testing conditions of a real-time system are similar to the simulation studies.…”

“…The switched reluctance motor (SRM) is a strong contender to conventional motors due to its distinctive features of rugged construction, absence of permanent magnets, high starting torque with low starting current, low manufacturing cost, wide speed range with more field weakening region and inherent fault-tolerance [2,3]. Due to these distinctive features, SRMs are exceptionally attractive and have become a prominent candidate in industrial, residential, commercial, and transportation sectors such as electrified vehicles [3,4], integrated motor drive and battery chargers [5,6], renewable power systems [6][7][8], aircraft starter/generator [9,10], and ultrahigh-speed applications [11,12].…”

Bidirectional multiport solar‐assisted SRM drive for pure electric vehicle applications with versatile driving and autonomous charging capabilities

“…The last two decades have seen a lot of progress in increasing the efficiency of PV arrays and work towards reducing their cost [35]. A considerable amount of work is done in the area of PV powered drives and is available in the literature [29,32,36,37] but very few are based on integrating grid, PV panel, battery and SRM to achieve various modes of operation using a single converter with a minimum number of switches. In [37], an SRM-based multiport bidirectional drive for PV-assisted electric bus is discussed.…”

FV-RES ile Beslenen Anahtarlamalı Relüktans Motorun Analizi

“…Son kırk yılda sürücü teknolojisindeki gelişmeler sayesinde klasik elektrik makinelerine alternatif olarak düşünülen Anahtarlamalı Relüktans Motorlar (ARM) diğer doğru akım (DA) motorlarına ve asenkron motorlara kıyasla yapısının basit, atalet momentinin düşük, imalatının ucuz olması ve yüksek hızlarda çalışabilmesi özelliklerinden dolayı makine sanayinde hızla yerini almıştır [5][6][7]. Yenilenebilir enerji kaynaklarıyla beslenen motor çalışmaları incelendiğinde ARM ile yapılan çalışmalar azımsanamayacak kadar çoktur [8][9][10]. Bu çalışmaların çoğu su pompalama sistemlerine odaklanırken, araştırmacılar motor yükleri olan sistemlerin kontrol tekniklerini ve performanslarını da araştırmışlardır [11].…”
