In this paper, a new developed quasi Z-source inverter is proposed. This new topology is based on a new hybrid-cell which is combined of a diode cell and a capacitor cell. The proposed inverter is called discontinuous diode capacitor assisted quasi Z-source inverter (DDCAQZSI). This inverter is analyzed in three modes: two-cell QZSI, three-cell QZSI and n-cell QZSI. In all above mentioned topologies the structure is completely analyzed and the equations of the boost factor, diodes and capacitors voltage stresses, input dc link and inductor’s current are calculated. According to the obtained results, the boost factor of the proposed inverter is increased by increasing the number of used proposed basic units. Then, the accuracy performance of the proposed topology and its obtained equations are verified by the simulation results. The simulation results done in EMTDC/PSCAD software program and on the two-cell DDCAQZSI.

This paper proposes a new boost converter topology to address the compatibility problem with a high voltage gain compared to the conventional boost circuit, which is highly proper for renewable energy resources and DC applications. In contrast to similar boost converter configurations, the proposed topology has fewer semiconductor components. Furthermore, the output stage is removed, as the switched inductor is developed by replacing two diodes with two capacitors. Moreover, the symmetrical circuit makes design and analyses less complicated. The operation modes and the steady-state analysis are accomplished in the current conduction mode. The converter simulation is carried out with MATLAB Simulink and Script so as to obtain the typical waveforms of the DC-DC converter.

Recently, the nested neutral point clamped (NNPC) converter has been developed for medium voltage applications. This converter has been considered for its desirable properties, such as application in a wide range of voltages, the low voltage stress on the switches, and excellent output waveform quality. This study presents a fast open-circuit fault detection method in semiconductor switches. The proposed method only requires the measurement of output voltage. The output voltage of the converter is investigated in different switching states. If there is a discrepancy in the converter output in normal mode and after the fault, the defective switch is identifiable. The proposed method has been investigated in the MATLAB Simulink environment under different scenarios. The simulation results confirm the desired performance of the proposed method.

A transformerless multi-input soft-switched high step-up switched-capacitor converter (SCC) suitable for high-power and high-voltage applications is going to be introduced in the present research. Zero voltage switching (ZVS) operation is provided for all power MOSFETs and diodes of the proposed topology by using active clamp circuits. Soft switching operation eliminates or significantly reduces the loss of switching so that high values of efficiency could be obtained. Moreover, the switching frequency could be highly increased as a result of soft switching operation. High switching frequency brings about high power density and passive components size reduction. Furthermore, Cockcroft-Walton voltage multiplier (CW-VM) units are employed to reach high values of voltage conversion ratio without applying high voltage stresses on the components. To approve the proper function of the proposed converter, a three phase prototype having three cell voltage multiplier (VM) units, 40 V input voltages, 925 W output power and 385 V output voltage is simulated at 150 kHz switching frequency.

High torque density is a significant criterion for electric vehicle applications. In the context of torque performance, firstly, the average torque of the motor should be improved, and, secondly, the torque ripple of the machine must be at a satisfactory level. Switch reluctance motors (SRMs), as an alternative, pass the first criterion. However, the torque ripple of the SRMs can be problematic for the users. Various methods have been used for torque ripple minimization, and most of them are related to structural techniques. However, these methods cannot be considered as the optimal ones. In this article, a 3-phase switch reluctance motor with 18 stator poles and 12 rotor poles (18/12) has been introduced, designed to be used in electric vehicles. The torque ripple of the motor is optimized using the Ant Lion Optimization (ALO) algorithm, which is a metaheuristic approach, and the result of the optimization problem is compared with the initial machine. The mathematical basics of the algorithm and performance parameters, such as the convergence speed, are discussed and compared with other optimization algorithms to declare the advantages and disadvantages. Lastly, the electromagnetic analyses of the proposed motor are performed using 2-D finite-element analysis.

In this work, a novel topology of high voltage rate DC-DC topology with high output voltage and high efficiency is proposed for photovoltaic application according to magnetic inductor and switching-capacitor unit (SCU). SCU increases the output voltage and acts like a voltage clamp and decreases the maximum blocking voltage of the switch. Thus, a low rated and cost power switch can be used in the recommended topology. Additionally, in this converter one magnetic core is used. The magnetic inductor technique is one method to enhance the output voltage without increase of the MOSFET duty cycle which is utilized in the proposed converter. As a result, using magnetic inductor and SCU, the output voltage of the recommended topology is increased with small peak voltage of the semiconductor, low elements count, low switch loss, and high power. The other benefit of the presented topology is the zero-voltage switching (ZVS) and zero-current switching (ZCS) of diodes. In order to demonstrate the accomplishment of the proposed structure, the technological expression, numerical analysis, and comparison survey with same family DC-DC converters are prepared. Eventually, experimental results with 200 W load power are presented to verify the mathematical survey.

A new non-isolated cubic converter has been suggested for applying in renewable systems due to the high voltage gain and continuous input current. Moreover, the low stress on the semiconductors is an other benefit which decreases the losses. The base of the topology is a combination of two Boost converters and a Buck-Boost converter which two capacitors are series in the output terminal. The mathematical calculations have been done in CCM. Two comparisons have been done which are for non-ideal voltage gain and the structural features of the proposed converter and some new suggested converters. The maximum voltage gain has been achieved to 22 for the 160 W output power and 50 percent duty cycle. The simulation results have been obtained by PLECS and illustrated.

Although Model Predictive Torque Control (MPTC) method is considerably noticed during recent decades in literature due to its ability to direct control of several criteria (such as torque and flux), it couldn’t find a remarkable role in industrial applications yet. The main challenge is vector selection when the focus on promoting one criterion will cause to lose the others. To solve the conflict, many different methods have been introduced such as applying online weighting factors, ranking methods, sequential methods which all have pros and cons. The proposed method has been designed to select the best vector by considering both criteria (Torque and Flux) impartially. Comparing the results shows, by applying the method, torque ripples are decreased while the other features remain unchanged.

Lack of permanent magnet, low cost, significant constant-power speed range, high loadability, and high efficiency of SynRMs, have made these motors an attractive option In different applications such as traction and aircraft. Due to the saliency on the rotor of SynRM, calculating the exact value of the initial position is inevitable in sensitive applications. Also, Initial rotor position information is required to have high-performance control and achieve high starting torque. In this paper, different methods of initial rotor position estimation consisting of symmetric DC pulse injection, high frequency pulsating voltage injection, and high frequency square-wave signal injection are studied. These methods are described in procedure aspect, simulation under different rotor position conditions are discussed, and the performance of each method in different initial positions is surveyed. Finally, a comparative study between different methods in terms of performance accuracy, implementation complexity, convergence time, motor parameters dependency, and etc. based on simulation results are provided.
