Testing of high power machines requires a significant investment into sophisticated equipment and floor space. Over the years, various methods aimed at reducing the cost have been developed, including, for example, mixed frequency testing (also known as synthetic loading) and back-to-back testing. While most of these techniques can be directly applied to multiphase machines as well, a particular stator winding topology - namely, the use of multiple three-phase windings, leads to a possibility to realise regenerative testing of the machine by operating some three-phase windings in motoring and some in generation. As a consequence, testing can be conducted without the need to have a loading machine and with very small energy consumption, governed by the combined machine and inverter losses. The paper describes application of regenerative testing in conjunction with machines with an even number of three-phase windings and details the control scheme used for a permanent magnet six-phase synchronous machine. Full power testing is enabled without the requirement for a mechanical load. Simulation and experimental results, illustrating the operation of one three-phase winding in motoring and the other in generation and collected from a 150 kW rig with a permanent magnet synchronous machine, are included.

A multi-copter or drone is a small, typically unmanned helicopter having more than two rotors. As the use of multi-copter has increased rapidly in recent years in a wide range of field such as military, agriculture, logistics, academic, surveillance and leisure, technical requirement for long-term use are inevitably followed. As a limitation on the long-term use of the multi-copter, excessive heat generation of the driving motor is regarded as one of the main causes. In order to solve this problem, it is essential to design an optimal heat dissipation structure. In this study, 3D computational fluid dynamics investigation and experimental verification have been performed to evaluate the effectiveness of ventilation holes on the cooling performance of the outer-rotor type BLDC motor used for a multi-copter. Then, adequate ventilation hole design is suggested through the comparative analysis of main heat transfer path and dominant internal flow path via Computational Fluid Dynamics.

Direct torque control with space vector modulation (DTC-SVM) is one of the best methods for controlling the electromagnetic torque of permanent magnet synchronous motor (PMSM) drives. This method grants excellent dynamic closed-loop torque-control performance. In this article (in Part 2) a simplified version of the new DTC-SVM method presented in Part 1 is presented. Also, it is shown that the simplified version has somewhat lower but still very high overload-capabilities. The adaptive voltage vector calculator mentioned in Part 1 is detailed in this Part. Finally, an analysis of the torque-ripples in the extra heavy overloading region is carried out at the end of this article.

In this paper, the excitation controlling structure for a synchronous generator with a field-controlled dc exciter is presented. Control unit represents a microprocessor-based device with buck converter within its power stage. Presented controlling structure offers a novel solution with a exciter self-excitation path. Namely, a buck converter is supplied directly from the dc exciter stator terminals, which are also used for the excitation of the synchronous generator field winding. However, since the field voltage of the synchronous generator varies significantly for the different modes of operation, especially during transients, this introduces significant nonlinearity in the control system. Additional blocks and loops in the control structure are avoided by introducing the appropriate linearization. Presented solution offers better large signal performance of excitation control system during transients, and some cost benefits compared to the more common solution proposed in IEEE 421.5 standard model DC4B, with synchronous generator self-excitation path established via its terminal voltage. Pole-zero cancellation excitation controller parameter tuning technique is, also, presented. Dynamic performance of the presented controlling structure is verified through the set of simulation and experimental tests presented in the paper. The simulations are carried out using the full order generator and exciter models. The experimental tests were carried out on a 15MVA synchronous generator.

Normally, a contactless energy transfer (CET) system contains multiple power transfer stages, which leads to a decreased efficiency factor and higher overall system cost. In this case, the primary side rectifier stage is based on hard switching topologies. This paper proposes a three-phase direct matrix converter controlled with space vector modulation in combination with a delta-sigma modulation on the primary side. Compared to other control strategies, this allows to obtain a sinusoidal mains current and therefore constant input power with a single converter stage. In contrast to other control strategies, which either do not reach a sinusoidal mains current or are not based on zero current switching, this method combines both. The detailed analytical theory of the control strategy is presented and the results are verified with measurements of a prototype system.

In this paper, the distributed generation (DG) inverter design based on unified power quality conditioner (UPQC) configuration is presented to solve the power quality problems for sensitive load under weak grid condition. The integrated DG consists of a series connection inverter and a shunt connection inverter. The series connection inverter acts as a dynamic voltage restorer (DVR) to mitigate voltage problem due to cable impedance in submarine cable and fluctuated load. The shunt connection inverter works as a back-up power source like PV system with Maximum Power Point Tracing (MPPT) when the voltage problem is seriously lower or higher than the operation standard. Battery system, as a back-up source when low irradiance condition, will be considered in this paper too. This paper describes a simple method for controlling the series connection inverter while the shunt connection operates as a back-up for sensitive load. Finally, the proposed method for integrated PV source is verified through the PSiM simulation.

Switched reluctance machines (SRMs) exhibit the advantages of low-cost production and high reliability. Position sensorless control can contribute significantly to further improve these properties. Due to the salient structure of the SRM, the stator inductance can be used to determine the rotor position $theta_{mathrm{e}}$ from injected current peaks at standstill and low speeds. Exact torque and force control of SRMs requires highly accurate information about the machine's rotor position. Therefore, the purpose of this paper is to expose the advantages of position estimation algorithms implemented on field-programmable gate array (FPGA). The algorithm includes an inductance identification procedure and sophisticated signal filtering. Besides improvement measures based on modeling and signal conditioning, a method for reduction of the injection currents is demonstrated and evaluated. The developed algorithm considers the mutual coupling effect and is verified by simulation and experiment.

In the last decade small scale hybrid renewable energy microgrids have been considered a suitable option for energy access in isolated areas where grid extension is economically unfeasible. A techno-economic feasibility study on an off-grid renewable energy microgrid for a greenhouse in Oradea, Romania, is carried out in this paper in order to meet the electricity demand in a reliable, sustainable and cost-effective manner. The microgrid consists of a geothermal energy generator, a biomass generator, a photovoltaic generator and battery storage to supply a vegetable greenhouse. The microgrid works islanded. The capacity of each generator is optimized with regard to the needs of the load and the minimum net present cost of the microgrid. Finally, sensitivity analysis is performed to determine the dependency of the energy costs due to the variable price of the biomass resource, the increase in the load demand and the energy management dispatch strategy.

Load regulation is a key performance indicator of inverters. Therefore, analysis of load regulation for series and parallel output inverters is proposed. The operating principle and control strategy are illustrated. Influence of different parameters on load regulation at series and parallel output modes is analyzed in detail. Finally, simulation and experimental results verify the analysis by a l-kVA series and parallel output dual-buck half-bridge inverter. The simulation and experimental results demonstrate that the load regulation of the inverter at both output modes is good and same when the output power at both modes is same and the output voltage at series output mode is twice that at parallel output mode.

There are different approaches to current Total Harmonic Distortion (THD) minimization – frequency domain or time domain THD computation and global or constrained optimization problem formulation. Time domain constrained optimization problem formulation seems to be most adequate from computational efficiency and robustness perspectives. The paper presents time domain constrained optimization results of current THD / harmonic loss for a two-level three-phase inverter.
