Multilevel inverters are used in various applications because of their intrinsic merits. One of the common applications of the multilevel inverters is the power quality (PQ) improvement devices such as the dynamic voltage restorer (DVR). An important in the DVR is how to obtain the DC source required by the inverter used in DVR. As providing the DC voltage source is challenging and costly, the number of required independent DC sources should be minimized. However, most of the multilevel inverters require a number of floating DC sources. In this paper, a 7-level inverter is proposed for the DVR application which requires only one DC source. It should be noted that for the same number of levels, the cascaded H-bridge (CHB) multilevel inverter will require at least (if it is asymmetric) two DC sources. On the other hand, the single-DC-source multilevel inverters such as the flying-capacitor (FC) and the neutral-pint-clamped (NPC) topologies require high number of switches and the DC source utilization factor is low. The proposed multilevel inverter requires one DC source and offers higher number of voltage levels to number of elements. The performance evaluation of the proposed multilevel inverter based DVR is undertaken with the simulations using MATLAB/Simulink.

In this paper, a novel design of the DC-DC converters has been introduced. The voltage gain has achieved high values by the lower value of the duty cycle. Besides the Cubic form of the voltage gain, the normalized value of the current stress of the switch diodes has been low. In addition, continuous input current ripple has decreased the current stress of the input filter capacitor as well as its capacitance value. The proposed converter has been designed for the continuous current mode. Moreover, the converter has been discussed in both continuous/discontinuous current modes. Furthermore, the advantages and bold points of the converter have been expressed in the ideal mode. Finally, the simulation results besides the experimental outcomes have been presented and compared. In addition, the prototype has been designed for 80 W output power.

This paper proposes a non-recursive controller for three-phase grid connected converters based on lyapunov direct stability theory. In the proposed controller, the control law only depends on the input signals and does not depend on the previous input samples, i.e. it is memoryless. The control law is comprised of two part. First part is to determine steady-state value of the control law and the second is for controlling transient behavior and satisfying global stability features. The proposed controller is validated using simulation of a 5kW three-phase grid-connected inverter in MATLAB/Simulink. Results imply on the exactness, robustness and implementation simplicity.

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.

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.

Converters with wide range output voltage play an important role in some specific industrial applications. Using traditional DC-DC converter for this reason brings many challenges. In the full-bridge converter, high conversion ratio of the transformer and voltage drop on the leakage inductance, limits the converter gain. Moreover, drastic changes in the output voltage cause the linear controllers to malfunction. In this paper a design is proposed for the full-bridge converter with hysteresis controller to prepare ultra-wide output voltage range. The feasibility of this converter which is used phase-shift modulation along the adaptive band nonlinear hysteresis controller is investigated with converter modeling and simulation results.

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.

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.

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.
