“…However, the topologies projected as the most attractive and with the highest market rate are those based on semi-variable speed machines (SVSM) and fully variable speed machines (FVSM) [4]. Within the SVSM, it is possible to mention the doubly fed induction generator (DFIG) [5]. In the FVSM, there are the permanent magnet synchronous gener-ator (PMSG), wound rotor synchronous generator (WRSG) and squirrel cage induction generator (SCIG) [6].…”

This paper proposes the utilisation of the direct matrix converter (DMC) to regulate the power transfer between a permanent magnet synchronous generator (PMSG) based wind energy conversion system (WECS) and the power grid. By connecting the PMSG at the output terminals of the DMC, control actions are simplified, implementation is facilitated since fewer sensors are required, and a WECS with a more compact structure is achieved because it is not necessary to use a transformer to compensate for the DMC voltage ratio. The DMC operation is controlled by the singular value decomposition (SVD) modulation technique and the four‐step switching strategy. For power regulation, an maximum power point tracking (MPPT) algorithm based on the wind turbine power curves technique is used in conjunction with the field‐oriented control technique and a proportional‐integral compensator. In the developed prototype of the WECS described, modulation, MPPT, four‐step current switching, control algorithms, and signal measurements are implemented on a single microcontroller unit. Finally, experimental results demonstrate the effectiveness of the proposed WECS in regulating the transfer of active and reactive power adequately and simultaneously with the power grid.

SummaryBridgeless ac‐dc converters are the optimal choice for many applications, as they offer many advantages such as low distorted supply current, high power factor, and improved efficiency. This paper presents a new topology for a single‐phase bridgeless ac‐dc converter. The proposed hybrid topology is based on integrating the inverting and non‐inverting buck‐boost dc‐dc converters that are connected to the ac supply through an LC filter. To insure sinusoidal supply current, the proposed hybrid bridgeless ac‐dc converter is operated in discontinuous current mode. The proposed converter has many merits, such as a reduced number of components, enhanced efficiency, and soft start‐up capability. The operation modes and design of the proposed converter are presented. In addition, a design method is proposed for the input LC filter to minimize the voltage stress across switches. Moreover, a small signal model for the proposed converter is developed. The proposed converter topology is simulated to evaluate the dynamic behavior and verify the accuracy of the presented small signal model. Furthermore, an 850 W prototype is developed to validate the features of the proposed converter experimentally. Tight voltage regulation, sinusoidal supply current, and near‐to‐unity power factor operation are observed from the results, regardless of supply or load disturbances.

In this study, a bidirectional DC-to-DC quadratic converter (BDQC) is designed and developed for the motoring and regenerative braking (RB) of a permanent magnet brushless DC (PMBLDC) motor for a light electric vehicle (LEV) application. A PMBLDC motor is deemed more suitable for an electric vehicle (EV) due to its high efficiency and torque density. In the present work, a BDQC of 1 kW is designed to drive a 1.1 HP PMBLDC motor through a conventional voltage source inverter (VSI). An EV’s load cycle is emulated using a highly inertial load driven by a PMBLDC motor during the converter’s boost mode operation. RB is a crucial factor in extending the driving range of EVs by efficiently utilizing battery power. The converter operates in buck mode during RB, and simultaneously, the back electromotive force (EMF) of the PMBLDC machine is boosted by the self-inductance of the PMBLDC motor and the VSI. The braking technique used in this work eliminates the traditional drawback of RB in buck mode, as the power is extracted even when the motor’s back EMF is lower than the battery’s voltage. The control strategy has been implemented using the TMS320F28335 DSP controller for a developed converter prototype of the converter and driving the PMBLDC motor. The experimental results are compared to the simulation results, and a good alignment has been found.
