This paper presents behavior of a double-input/single-output (DISO) zeta converter by applying interleaved switching pattern in continuous conduction mode (CCM). This converter is implemented by combining two H-bridge cells and a conventional zeta converter, based on DISO buck-boost topologies. The converter can be utilized in either step-down or step-up modes. By adopting the interleaved switching pattern, a delay time is generated between gate pulses of H-bridge cells transistors. As a result, the converter output voltage can be varied by changing the delay time while the pulse duty cycles are kept constant. Moreover, the output voltage ripple, which is depended on the duty cycles is also kept constant. According to the chosen duty cycles and delay time, the converter can operate either in step-up or step-down modes. The output voltage ripple value of the proposed converter is less than that of both buck-boost converters, and the output voltage polarity is positive as opposed to DISO buck-boost converter. As the input filter inductor is placed in a parallel branch, adding several numbers of H-bridge cells in series as the input stage of zeta converter is very easy and does not need any changes in the formation of the converter components, which is a great advantage of utilizing zeta converter in comparison to cuk and SEPIC. Steady state analyses and calculations are done, and the proposed converter is simulated in both step-up and step-down modes.

Nowadays, due to availability of powerful signal processors, the digital control approaches, such as deadbeat control, have received considerable attentions. The deadbeat controller offers critical advantages, such as constant switching frequency, fast dynamic response, and low settling time. Nevertheless, the parameter dependency of the deadbeat controller has always been questioned. In this regard, this paper proposes a forward-backward discretization method for a single-phase active power filter to be used for deadbeat controller design. This procedure offers high accuracy in modeling and at the same time simplicity in designing the deadbeat controller. The proposed discretization approach reduces the required two forward steps prediction down to only a step. The superiority of the developed controller is then confirmed through extensive simulations.

Axial-flux permanent magnet (AFPM) machines are one of the potential candidates for the future higher performance drives due to their compact structure, high power/torque density, and lower losses. Nevertheless, one of the problems with these machines is the high harmonic components in their back electromotive force (EMF), which is needed to be reduced in the design process so as to compete with other electric machines. In addition, in order to easy startup and also less noisy performance, the torque ripple of the AFPM machine should be reduced. Both the back-EMF and torque ripple are relevant to rotor magnetic flux distribution, which is manipulated by the shapes of magnets. In this regard, coreless double rotor AFPM machines with different magnet shapes are designed and analyzed in this study using 3D finite element analysis (FEA). According to the investigations, magnets with sector-like shapes offer better performance indices compared with other types of magnets. Thus, the machine designed with the best magnet shape is then selected to evaluate the proposed design performances in terms of different air-gap and magnet thicknesses.

This paper introduces a new non-isolated high gain dc-dc topology with magnetic coupling and voltage multiplier technique (VM). The high voltage conversion ratio can be achieved by selecting the suitable turn’s relation of the magnetic coupling. The VM circuit has been utilized for further extending the voltage rate. Also, the voltage spike through the switch can be clamped by VM circuit which leads the decrease the peak voltage through the switch. Moreover, there is only single switch, so the control circuit will be simple and a switch with lower conducting resistance can be selected. For validating the proficiency of the proposed structure, technical analysis and simulation results with 200W power level and 25 KHz operating frequency is provided. Furthermore, the comparison survey with other topologies are prepared for demonstrating the effectiveness of the recommended converter.

A high-efficiency and a high conversion gain DC-DC converter is introduced in this paper to apply sustainable energy sources into dc nano-grid. The introduced topology takes the property of the coupled inductor (CL) method to obtain a declined voltage stress of the semiconductor devices and high voltage conversion ratio. The MOSFET voltage stress is remarkably decreased constracted to the output high voltage. Thus, a low on resistance MOSFET and low rating voltage is used to increase the efficiency of the suggested topology. Moreover, the CL application obviates the reverse recovery losses of diodes. The steady-state analysis and operation principle of the suggested configuration are elaborated. Besides, the introduced configuration superiority is illustrated over many alike most momentous recently proposed DC-DC configurations in the section 5. The simulation results demonstrate coherence with the theoretical study with a 340 V output voltage and a 340 W output power. The topology demonstrates a 96.5% peak conversion efficiency.

In this study, a model predictive control (MPC) method is used to control a four-leg voltage source inverter in a stand-alone microgrid. The proposed method aims to regulate the voltage of the inverter so that the cost function of the MPC becomes minimum. Minimizing the cost function, the output voltages will become balanced even under unbalanced load conditions. The suggested controller is validated through Simulink/Matlab. Moreover, the outcomes are compared with the conventional double-loop proportional-integral controller. It is shown that the output voltages have lower THD and phase unbalance rate using the suggested MPC. Next, it is argued that neither of these methods can have control over neutral-to-ground voltage, which is a critical power quality issue in microgrids with sensitive loads. As the MPC has the potential to consider several parameters; therefore, it is recommended to manipulate the MPC cost function to compensate for output voltages and reduce the neutral-to-ground voltage, simultaneously.

Railway power conditioners (RPCs) are familiar as a power electronics compensator in electric railway power systems (ERPSs). Due to the variable with the time features of electric railway loads, to improve the performance and stability of the RPC against changes, nonlinear control is a good option. In this paper, due to the importance of exact circuit modeling, an accurate modeling strategy based on space-state model (SSM) and dynamic switching pattern is proposed. Deriving the extracted equivalent model and mathematical equations, a sliding mode control (SMC) system according to the exponential reaching law in the dq frame is adopted. Finally, the presented control method is simulated for V/V transformer by Matlab/Simulink software. The simulation results are provided to reveal that the proposed strategy is very effective.

In cascaded H-bridge (CHB) converter, despite its high modularity, each h-bridge cell requires an isolated dc-source. The phase-shifting transformer in cascaded h-bridge (CHB) converter is its main drawback. New topologies have been introduced with a reduced number of DC sources e.g. MMC. But it needs lots of semiconductor components. A new topology is proposed in this paper which is called cascaded flying cells (CFC). This topology provides high modularity and uses a single DC-link per phase. A sorting algorithm is proposed in this paper by which the voltages of flying capacitors in the converter cells are kept balanced with a constant switching frequency. Compared to several reduced count multilevel converters, it provides high modularity and better controllability of capacitor voltages. The proper operation of a five-level CFC is simulated in both steady-state and dynamic conditions in MATLAB/SIMULINK environment.

This paper proposes a zero-voltage transition (ZVT) PWM high step-down converter. The proposed converter consists of a high step-down interleaved buck converter (IBC) and an auxiliary circuit with only one switch. The auxiliary circuit provides zero voltage switching (ZVS) condition for the IBC switches, while zero current switching condition is achieved for the auxiliary switch and diodes. Due to utilizing a high step-down IBC, the voltage gain of the converter is much less than the conventional IBC. The proposed converter is analyzed, and its operating principles and design procedure are presented. In order to verify the analysis, the simulation results of a 120W prototype converter operating at 100kHz are reported.
