“…The selection of an appropriate electric generators is a tedious work. Several generators commonly used for generation are doubly fed induction generator (DFIG), 42 permanent magnet synchronous generator (PMSG), 43 and switch reluctance generator (SRG) 44 . In doubly fed induction generator, rotor and stator contain winding which increases losses and weight of the shaft and hence reduces its efficiency.…”

Power generation through renewable sources using a multistage power conversion process was plagued with efficiency and reliability issues. It led to the evolvement of a novel universal converter for the simultaneous interfacing of solar and wind energy. Solar energy is extracted using a multiphase boost converter, while a 2n converter with a switch reluctance generator has been used for wind energy extraction. In this paper, a novel universal converter is used to integrate both solar and wind energies, which will reduce multiple stages of the power conversion process. This converter generates an output voltage of the sino‐square waveform, which is a combination of a sinusoidal and square waveform. Enhanced efficiency and competency of this sino‐square waveform in domestic and industrial applications have been validated with a systematic comparison with conventional square waveform. These two waveforms have been compared based on various harmonics generation, total harmonic distortion (THD), and switching losses. The proposed topology has been validated with an experimental setup using a PV emulator for solar energy. Wind energy has been implemented using an induction motor with switch reluctance generator.

“…The doubly fed induction machine (DFIM) working as a generator is getting a lot of attention in the present time [1][2][3], especially in the field of renewable energy applications such as generating the electricity from wind natural sources. In the other side, usage of DFIM as a motor is still limited and few studies have been introduced about it [4][5][6].…”

The paper presents an applicable sensorless model predictive direct torque control (MP DTC) technique for a doubly fed induction machine (DFIM) drive operating in motor mode. An effective sensorless procedure is presented to get a robust drive performance for the desired speed change. The advantage of the proposed sensorless topology is that there is no necessity for estimating the flux, as presented by various searches before. A dSpace 1104 prototyping control board is used to implement experimentally the control procedure. Obtained results prove the validity of prospective control approach in obtaining a high dynamic performance of the DFIM drive for the required speed changes.

“…The production of electricity from renewable primary sources is a matter that has been substantially addressed by the scientific community. Primary sources available include wind energy, which integrates most of the energy matrices in Asia, Europe, and North America [1]. Energy conversion systems from wind kinetic energy are commonly called wind energy conversion systems (WECS).…”

This article presents studies related to the driving and control of the switched reluctance generator in order to enhance its efficiency. This type of electrical machine is an option for wind energy conversion systems, favoring the generation of electricity in distributed generation systems and contributing positively to loads without access to the main grid. The studies developed in this paper verify the possibility of controlling the output voltage of the switched reluctance generator in parallel with an efficiency tracking technique acting on the switching angles of the power converter. Simulation and experimental results are presented in order to verify the feasibility of implementing this technique to enhance the efficiency of the generator.
