“…where the magnetic self-inductance coefficient (L j ) was introduced and it is considered, in this analysis, not dependent on the phase current, i j . On the other hand, it depends on the rotor position and should be considered non-linear [50]. Using (5), the torque developed by each phase and represented in (3) can be rewritten as:…”

Reliability in the electrical drives is becoming an important issue in many applications. In this context, the reliability associated to the switched reluctance machine (SRM) is also an important area of research. One of the major problems, that strongly affect its operation, are drive power semiconductors faults. Typical power converter topologies used in SRM drives cannot handle faults in their power semiconductors. So, this paper presents a power converter topology that provides fault-tolerant capabilities to the drive under a switch fault. This power converter will be used considering that a change in the direction of the current that flows in the SRM windings does not affect the behavior of the machine. Besides that, the proposed power converter will allow to generate multilevel phase voltages in order to apply different voltage levels as function of the SRM speed. A laboratory power converter was developed to test the SRM drive in normal and faulty conditions. From the obtained results it was possible to verify the fault-tolerant capability of the drive under switch faults in different devices and failure modes. It was also possible to confirm the multilevel operation of the drive.

“…There are, in many places around the world, pumping systems using internal combustion engines (mainly diesel) with the inherent disadvantages of fossil fuel prices (including transportation costs), environmental pollution (noise and smoke), high maintenance costs, low reliability and low efficiency. To overcome some of these disadvantages, several solutions of pumping systems powered by SPV have emerged in recent years [8]- [10], providing low operating and maintenance costs, robustness, reliability and autonomous operating capacity. Typically, water pumping systems are driven by direct current (DC) or alternating current (AC) motors [11]- [13].…”

“…A detailed comparison between permanent magnet DC motors (PMDC) and AC motors for solar-powered water pumping systems is discussed in [14,15]. Switched Reluctance Motors (SRM) are also a suitable alternative for use in pumping systems due to their robustness, low inertia, low cost, simplicity of operation and potential to work in hostile environments, [10], [16]. In addition, this type of motor can be driven by a simple converter powered by a DC power source.…”

The present paper describes a solar photovoltaic (SPV) powered water pumping system employing a switched reluctance motor (SRM) and a merged Sepic-Ćuk DC-DC converter. The proposed solution was designed to use efficiently the available solar energy in order to supply water pumping systems. Solutions of this kind assume a special importance in the current scenario of natural and renewable resources optimization. The proposed DC-DC converter operates in continuous conduction mode (CCM), which combined with a maximum power point tracking (MPPT) controller, helps to optimize the power of the solar photovoltaic panel (SPV). The proposed DC-DC topology is characterized by high voltage static gain when compared with the classical boost topology and reduced voltage stress across the power switch and diodes. Several simulation and experimental results are presented in order to confirm the characteristics of the proposed solution for water pumping systems.

This work deals with an efficient and reliable solution of a standalone solar water pumping system using a 4-phase SRM (Switched Reluctance Motor) drive. Only a mid-point converter is used to drive the SRM as well as to achieve the MPPT (Maximum Power Point Tracking Algorithm) operation. The elimination of DC-DC converter offers a fast dynamic response with enhanced system efficiency. An online flux optimization with single pulse mode of SRM drive is developed and implemented. The developed control scheme eliminates the need of any phase current sensor, and the motor speed is fully governed by the available PV array power. The developed control technique removes the need for any phase current sensor and the speed of the motor is regulated through available solar power. A deviation free MPPT technique is also implemented in this system to overcome the drift problem present in the conventional P&O (Perturb and observe) technique. The appropriateness of the proposed system with developed control is demonstrated through its performance assessment utilizing simulation and test results obtained through an experimental prototype.
