Special Issue Information

Dear Colleagues,

We invite you to contribute to this Special Issue in Sustainability with your latest research on power electronics topologies, monitoring, operation, and control schemes in Variable Speed Drives (VSDs).

Controlling DC and AC machines by power electronic converters has been considered the heart of power conversion systems in different applications such as industrial variable speed drives, electrical vehicles (EVs), trains, AC/DC shipboards, wind turbines, and microturbines. On the other hand, electrification of various traditionally inefficient systems such as transportation systems is at the forefront, wherein they have highly demanding performance requirements from the electric machines and drive systems. VSDs contribute to more sustainable usage of electric power with reducing energy consumption, especially in variable flow applications such as fans, pumps, or compressors.  Currently, there are still some challenges in terms of the system cost, efficiency, and robustness which must be overcome by the development of new power converter topologies and control schemes.

This Special Issue requests articles that address the original advancements, technical challenges impeding advancement, and novel solutions to these issues. Topics of interest for this Special Issue include, but are not limited to:

  • Sustainable drive system
  • Architecture and hardware design of VSDs
  • Speed control of AC machines
  • Speed control of DC machines
  • Speed/torque control of electrical vehicles
  • New power electronics topologies
  • Enhanced control schemes for VSDs
  • New modulation schemes for VSDs
  • Sensorless control for machine drives
  • Machine side control in wind turbines
  • Design for reliability, resilience, and robustness
  • Integration of renewable energy resources
  • Control and power-sharing between VSDs
  • Power quality aspects
  • Industrial, experimental, and hardware-in-the-loop tests and validation

Two of the main challenges of recent electric vehicles (EVs) are the charging time and high initial cost. To solve the problem associated with long charging time, the car manufacturers are moving from 400 V battery EV (BEV) to 800 V BEV, which enables the utilization of multi-level converters in EV applications. This paper presents a power conversion system consisting of a Vienna rectifier and a two/three level hybrid inverter as a machine-side inverter to drive a permanent-magnet synchronous motor (PMSM). The Vienna rectifier improves the quality of the grid-side current and provides a regulated DC-link voltage. The proposed inverter, known as a 10-switch inverter, offers high output current quality with a lower number of active switches, making it compact and cost-effective. The field-oriented control (FOC), along with the SPWM modulation, is implemented to control the system. A reliable and cost-effective PMSM drive system demands sensorless control; therefore, a sliding mode observer (SMO) is used to estimate the rotor position and velocity. The accuracy of the proposed system was proved through the simulation results from MATLAB/Simulink. Full article

This paper proposes a novel high-gain AC-DC converter based on the Cockcroft-Walton (CW) voltage multiplier which can be utilized in motor drive systems with low input voltage. In this topology, use of the voltage multiplier and boost circuit results in the increment of converter gain which has a significant impact on the cost and efficiency of the system. Moreover, in this converter, the AC voltage is directly changed to DC voltage using the switching method in high frequency and, as well, the power factor is corrected. Besides, this high-frequency converter contributes to the reduction of output ripple. On the other hand, cost efficiency, the low voltage stress on capacitors and diodes, compactness, and the high voltage ratio, are achieved from the Cockcroft-Walton circuit. Furthermore, the hysteresis method is presented for converter switching to correct the power factor. The converter is simulated in MATLAB software to demonstrate the effectiveness of the suggested method. Lastly, a laboratory prototype of the suggested converter is built, several tests are done in order to verify the theoretical analysis, and comprehensive comparison with the state-of-the-art converter is done.

In this paper, a deadbeat predictive control (DBPC) technique for doubly-fed induction generators (DFIGs) in wind turbine applications is proposed. The major features of DBPC scheme are its quick dynamic performance and its fixed switching frequency. However, the basic concept of DBPC is computing the reference voltage for the next sample from the mathematical model of the generator. Therefore, the DBPC is highly sensitive to variations of the parameters of the DFIG. To reduce this sensitivity, a disturbance observer is designed in this paper to improve the robustness of the proposed DBPC scheme. The proposed observer is very simple and easy to be implemented in real-time applications. The proposed DBPC strategy is implemented in the laboratory. Several experiments are performed with and without mismatches in the DFIG parameters. The experimental results proved the superiority of the proposed DBPC strategy over the traditional DBPC technique. Full article
