The recent increases in the consumption of permanent magnet machines emphasizes the importance of designing the ones with interior permanent magnet (IPM) structures that have enhanced performances. This study designed and analyzed the rotor shapes of IPM machines. In this regard, six types of magnets for dual rotor axial-flux permanent magnet (AFPM) were modeled and analyzed using 3D finite element method (FEM). In order to minimize the number of variables of this study, all of the parameters including the size of the stators, machine’s height, diameter, and so on are considered to be fixed and only the magnet shapes were modified to compare the machine’s characteristics. When the machine’s performances were compared as a function of rotor shape, the machine with sector-like magnet demonstrated the best results in terms of electromagnetic torque, torque ripple, air-gap flux density, and back electromotive force (EMF), as well as total harmonic distortion (THD).

The suggested converter enjoys a wide output range from almost zero to 50V/20A. The crucial issue of applications with expansive voltage capacities such as cathodic protection applications, electric vehicle (EV) battery chargers, and photo-voltaic inverters is that the zero-voltage-switching (ZVS) is hardly attained at low outputs. The proposed converter employs auxiliary passive components to surmount this problem. Moreover, a parallel capacitor is implemented at the transformer secondary side to decrease the effect of the parasitic capacitors and provide a robust control system with less sensitivity to parasitic elements. Theoretical calculations and simulation outcomes confirm the veracity of the suggested method.

This paper introduces a stabilized high precision high voltage power supply for photomultiplier tubes. The output voltage can be adjusted from zero to -3kV and the nominal output current is 5mA. Both load regulation and line regulation values are below 0.01% and the output voltage ripple is less than 0.3V. This power supply can measure both voltage and currents. The input supply voltage is 220V ac and the output is short circuit protected. To verify the feasibility and functionality of the proposed power supply, simulations are performed. Moreover, a prototype is designed and fabricated. The results confirm that the presented power supply meet the specifications required for photomultiplier tube applications.

This paper compares the dynamic and static models of a Lithium-ion battery pack with its electrochemical model as energy storage of an electric vehicle according to the environmental protection agency drive cycles. The dynamic model or the RC equivalent circuit includes a voltage source and double parallel resistor and capacitor networks which are connected in series. The static model includes a voltage source and resistors. Given drive cycles, these models are compared in terms of the battery voltage, state-of-charge, and power loss in an electric vehicle in MapleSim software. Although the state-of-charge and power loss of both models are identical to each other, actually the terminal voltage of the dynamic model is close to the electrochemical battery pack. Indeed, the dynamic model accuracy is much more than the static model, especially when the vehicle velocity variation is high.

The Modular Multilevel Converter (MMC) has been recently accepted as an advantageous choice for high-voltage applications. However, for extending this topology to higher voltages, the number of its submodules should be increased. On the other hand, using high-frequency carrier-based modulation schemes is very popular for voltage-source converters; since they provide improved output quality, and don’t involve complex calculations. When this strategy is employed for MMCs, the number of carriers would increase for more submodules, and the control complexity and required memory become more as result. Moreover, synchronizing several carriers is another issue. In this paper, a novel PSC-PWM scheme with low control complexity is proposed. The number of carriers employed in the designed scheme is always two, and independent of the submodule numbers. Despite this fact, the benefits of the conventional PSC-PWM, like the excellent harmonic content for different operating points, are completely remained. The performance of the proposed method is validated through conducting simulations in the MATLAB/Simulink environment.

Inductive wireless power transfer (WPT) to a moving receiver (Rx) can be evaluated by the Rx displacements and rotations relative to the transmitter (Tx). Three degrees of freedom (3 DoF) in displacements and 3 DoF in rotations of the Rx can be defined. This research has designed a system with the highest DoF (6 DoF). The Tx has crossed dipole coils, and the Rx has the minimum number of coils for 3-D omnidirectional WPT. Unlike most studies on 3-D omnidirectional WPT, the Tx and Rx have flat structures in this study, which can be an essential advantage in transferring power to moving devices. Because of variable magnetic coupling, the compensation circuit has the LCC-S topology. With a 2.4 cm transfer distance, power transfer efficiency is higher than 80% in the Rx displacements, and the maximum transfer power reaches about 700 watts. The efficiency remains high in the Rx rotations around the z-axis (yaw rotations) with output power changes. The efficiency is also acceptable in the Rx rotations around the x and y axes (roll and pitch rotations). Therefore, the proposed WPT system provides 6 DoF with the flat Tx and Rx structures.

In this paper, a new extendable multi-input multi-output (MIMO) DC-DC converter is proposed. The proposed converter is based on active switched inductor (A-SL) network and voltage multiplier cell (VMC). The main feature of the proposed converter is a high-voltage gain and low voltage stress on semiconductors. The proposed converter can operate in a single-input multi-output (SIMO) mode. Generally, MIMO converters can combine different renewable energies such as solar panels (PV), Fuel Cells (FC), Batteries, and wind turbines, so it is expected that such systems work with high reliability. Therefore, it is essential to propose a suitable MIMO converter with a high-voltage gain. To realize the superiority of the proposed converter over similar MIMO converters, the suggested converter has been compared to other MIMO converters. Finally, to investigate a high-voltage gain (higher than 30), this converter is simulated in MATLAB/SIMULINK.

Two-level inverters are one of the most widely used inverters in the industry. The Space Vector Modulation (SVM) modulation is proposed in many cases to achieve the maximum capacity of the DC link voltage of the inverters. In this paper, the performance of the SVM modulation method in a detailed model of the electric vehicle powertrain system in various operating modes, including sub-modulation and over-modulation, is described. A real-time SVPWM algorithm for a three-phase two-level inverter is implemented using the DSPACE DS1104 board. Finally, this method is implemented in MATLAB software, and the performance is compared under different modes and switching frequencies.

A robust combined control method of grid-connected converters is proposed in this paper. The method regulates the grid current vector in a two-phase stationary frame using hysteresis controllers and a novel dynamic switching logic. It is model-free and has a simple control system structure with low online calculations. In addition, the method avoids any pulse-width modulation sub-system and reference frame transformation of either voltage or current. Moreover, fast dynamic power response and low current THD are obtained under the proposed dynamic switching logic. Furthermore, the proposed method is a good choice from the grid protection point of view due to a direct current magnitude regulation. Compared to the vector control method, the proposed control system lacks any grid parameter dependency, PI controller, and PWM-subsystem.
