In this paper, a high step-up dc-dc converter is proposed. The main feature of the proposed converter is its flexibility in developing and achieving different high voltage gains. This converter comprises of inductor-capacitor cells and with a higher number of cells, voltage gain increases. The proposed converter's operation principle is based on charging in parallel and discharging in series paths. Operation analysis and voltage gain and voltage stresses of semiconductors are calculated and contrasted with other converters to illustrate the prominent attributes of the proposed converter. Simulation results, which have been implemented via PSCAD-EMTDC, are presented to validate the performance of this converter.

Wireless power transfer (WPT) systems are power electronic converters which can be installed under the road and charge the butteries of the electric vehicles. High total harmonic distortion (THD) of the input current is an important challenge in WPT system design. In this paper a new topology is proposed for WPT systems to reduce their input current THD. In the proposed topology, a quasi-Z-source inverter (QZSI) is used in series with a LLC resonant network. In addition to the DC voltage boosting, QZSI shapes the input current. The simulation results verify the performance of the proposed structure in THD reduction and power factor correction in comparison with the conventional Z-source resonant converter.

In this paper, a soft-switching isolated dual active bridge bidirectional DC-DC converter is proposed. Bidirectional DC-DC converters have many applications for electrical energy storage systems. Dual active bridge structures are the basic structure of this application due to their higher power density and efficiency. But the leakage inductance of this converter leads to increased conduction and switching losses and reduces efficiency. Some techniques such as active snubber, active clamp and resonant circuits are applied to achieve soft-switching conditions for the converter in recent researches. However, additional elements and variable frequency are the main disadvantages of these techniques. In the presented converter, the soft-switching conditions is provided by use of phase shift control with no auxiliary switch or circuit. The switching frequency and resonance frequency are equal in this converter which results in simplicity of control circuit. In this survey, the proposed converter and operating modes are illustrated and experimental results are reported to demonstrate theoretical analysis.

Analytical modelings are not only rapid tools for the analysis of electrical machines, but also are precise enough compared to numerical methods. On the other hand, switched reluctance machines have non-linear magnetic features and doubly-salient configuration. Due to these features, finite element analysis (FEA) is usually applied to attain the main characteristics of the machine which is time-consuming. In this research, an improved non-linear magnetic equivalent circuit (NLMEC) for a fault-tolerant modular switched reluctance motor with three layers of C-shape stators is developed to achieve the main features of the motor. To clarify the accuracy of the model, a 3D finite element analysis is adopted, and the results are compared with analytical solutions. Thanks to FEA, it is elucidated that the results attained from the developed circuit are accurate enough in comparison with those issued from FEA. It is also illustrated that this method saves a large time compared to FEA, which is a valuable factor for preliminary design stages.

In this paper, a high-voltage resonant power supply for ozone generation is introduced. The proposed circuit includes a power switch, a resonant capacitor, and a step-up transformer. In addition, it operates under the zero current switching (ZCS) condition which results in higher efficiencies. The simulation results show a sinusoidal output pulse with peak value of 8kV and 1.66us pulse width which is generated from 500V DC input voltage. A hardware prototype with 150V DC input and 2.4 kV output pulse has been implemented. The pulse repetition frequency is set to 15 kHz. The simulation and experimental results are presented in order to validate the converter as well as the operation circuit specifications.

In this paper, a new buck-boost dc-dc converter, which is applicable to renewable energy sources, is proposed. The proposed converter is capable of delivering the desired output voltage over a wide range of input voltage variations. Depending on the load requirements, by changing the duty cycle of the switches, the proposed converter can operate as a buck-boost converter. In this converter, the output voltage polarity is the same with the input voltage polarity, and the input has a common ground with the output. The voltage gain of the proposed converter is high compared to similar structures. The proposed converter is thoroughly analysed under CCM operation and simulated in the PSCAD/EMTDC software environment to confirm the mathematical analysis.

In this paper, a new extended quasi-switched Z-source inverter, using a switched-inductor cell, is proposed. The most important advantage of the proposed inverter is achieving the maximum voltage gain in the lower duty cycle with less circuit components than similar previous inverters, which causes the modulation index value increase. Furthermore, it leads to less power losses and less voltage and current ripples. The employed control method in this inverter is the pulse width modulation (PWM) simple boost control method. In this paper, theoretical analysis and comparison results of the proposed inverter with other similar ones are prepared. In addition, the experimental results reconfirm the accuracy of the proposed extended-qSZSI.

In this work, a non-isolated based DC-DC converter with high voltage conversion ratio is presented that is appropriate candidate for high voltage gain application such as Photovoltaic (PV) systems. The proposed topology combines coupled inductor and voltage multiplier (VM) circuit. By selecting the proper turn’s ratio of the coupled inductor winding, the wider voltage gain can be achieved. The VM circuit is used for further enlarging the voltage gain and also acts as a clamp circuit which provide low voltage stress through the switch. In addition, a diode has zero current switching (ZCS) condition in OFF-state which is main feature of the suggested structure. The proposed converter has used a single power MOSFET with less ON state resistance value. Hence, the control of the proposed topology will be simple and the conduction losses will be reduced by using only active switch with lower resistance. The operation principle, theoretical analysis and comparison study are accomplished in this study. Eventually, In order to ensure the proficiency of the presented structure, the experimental consequences with 25 kHz switching frequency is provided.

In This paper, a new post-fault control method for symmetric cascaded H-bridge multilevel inverters (CHB-MLIs) is proposed with the aim of the development of CHB-MLIs performance under faulty conditions due to decrease in common mode voltage (CMV). In other words, this technique addresses the exclusive process to select the optimal post-fault state among all available states possess the same amplitude of the output line to line voltages. As a result, this process leads to provide computed phase voltages references to apply to PWM block. Hence, this technique leads to decrease the common mode voltage and eliminate it under some desired output line-line voltages. Finally, the feasibility of the new technique is verified by MATLAB/SIMULINK for various faulty operating states.

A multi-level inverter structure with capacitance switching based technology is proposed in the conducted study. The dominant feature of this inverter is that the obtained waveform of the output is similar to the sinusoidal wave. The purpose of this method is to apply the partial charging to obtain several voltage levels from each capacitor, which can diminish the quantity and capacity of the capacitors. To do this, only two capacitors are applied to produce 13- level in the suggested circuit. Moreover, the proposed framework is successfully fabricated along with evaluating the total harmonic distortion. In the following, a recommended switching method is introduced that is capable to heighten the derived voltage levels without increasing the quantity of elements. Simulation protocols are reported to validate the truthful operation of the suggested multi-level inverter.
