the iron powder magnetic material has widespread applications in engineering. So appropriate measuring characteristics of this material especially B-H curve is essential in the design procedure of the inductor used in power electronics. One of the standard frames for measuring the magnetic characteristics of the iron powder is the toroid core. The accuracy of measuring the magnetic characteristics of the toroid core is affected by various uncertainties. One of this uncertainties is the non-uniform distribution of magnetic field in the surface of the core. This issue in presence of impurity and non-uniform distribution in core compounds can leads to the error in measuring the hysteresis loop and core losses. In this paper first, the analytical design of the dimension of the toroid core based on IEC Standard 60404-6 has carried out then the Finite Element Method (FEM) and Simulink model are used to confirm the analytical design. Furthermore, the designed toroid frame is manufactured and the result compared to each other. Eventually, the issues of impurity and non-uniform magnetic field distribution on the toroid core are investigated.

High voltage power supplies (HVPS) are widely used to supply vacuum tubes. Regarding to their high efficiency, resonant converters are a choice of HVPS structure. In this application, HVPS is faced with wide variation of the load power. On the other hand, output voltage regulation over wide load range is essential. However, there are several problems dealing with resonant converters such as output voltage regulation and low-efficient performance in a light load. In this paper, a control scheme for a series-parallel resonant converter is presented. This scheme regulates the output voltage of the converter over load variation range. A variable inductor placed as the series inductor in the resonant tank achieves constant maximum power factor. Output voltage is regulated by phase-shift method and the switching frequency is constant. Experimental results are presented to confirm the proposed method.

Rail transport is one of the transportation methods on earth that is very frugal in energy consumption. Electric railway technology has many advantages and disadvantages as well. The most important disadvantage of this technology is the creation power quality problems in the upstream power system. In other words, electric railway traction systems due to continuous load variations, Reactive power demand, asymmetry and harmonic Pollution can be challenged for the upstream power system. In this paper, after introducing the structure of the AC electric railway network and its related power quality issues, the railway power quality compensator (RPQC) is introduced. Also, in order to active power transfer between the various lines of electric railway, a railway interline power flow controller (RIPFC) has been introduced. The proposed structure RIPFC is in parallel, unlike the conventional one which is installed in series with the lines. RPQC and RIPFC contains two Separate single phase converters that are connected back to back (B2B) by sharing the same dc link. Extraction of compensating currents for RPQC and RIPFC is based on current measurement and its separation into active, reactive and harmonic components. Moreover, a controller is proposed to maintain the dc-link voltage. The simulation results using PSCAD/EMTDC are provided to demonstrate that the proposed strategies is very effective.

Dynamic Wireless Power Transfer (DWPT) systems are becoming an interesting option for charging EVs in urban and suburban areas, due to its advantages. Since Efficiency of these system is of major concern, maximizing transferred power efficiency is analyzed in this paper. Optimization of equivalent load resistance is proposed in this paper by using a DC-DC buck converter in the secondary side. Since the optimum load is a function of coupling coefficient which may varies for moving vehicles, an estimation method is proposed to calculate it dynamically. By using the estimated coupling coefficient, an optimum equivalent load resistance and the corresponding buck duty cycle is calculated and applied to the converter by PWM method to maximize the efficiency. In addition, a voltage regulation method is proposed by controlling the duty cycle of the primary side inverter. As a result, the load voltage is fixed at its reference value and a constant power is delivered to the load even if coupling coefficient changes. The proposed control method is applied to a DWPT system, where the simulation results indicate the effectiveness of the proposed method.

Cascaded multilevel inverters are usually used in a medium-voltage output. Hence, this converter has been declared as a vital substitute in the average-voltage inverter. In this article a novel structure for cascaded multilevel inverters have been proposed. Also, five algorithms are suggested to determine the amount of resources which are used in the new structure. The suggested topology has a number of benefits, including reducing the quantity of IGBTs and switches and required fee and installation area. Another benefit of the suggested structure is lower variety of the values of dc voltage sources in comparison with conventional structures. In this paper, the ability of proposed topology to produce all voltage levels with the result of the simulation is given to a17-level inverter.

On-road dynamic charging of electric vehicles with distributed generation (DG) sources has emerged recently as a cost-saving means for modern transportation. The resonant converter as a common WPT topology is not a suitable choice here due to several deficiencies. In this paper, a novel low-frequency multi-objective WPT topology, based on loosely coupled flayback converter with the compatible energy recovery circuit is proposed against the restriction of resonant converter. In this system, an input DG source (photovoltaic (PV)) produces its maximum possible power to supply the EV according to the MPPT algorithm. The remaining energy is stored in the back-up battery during each switching interval and can be injected to the EV drive train, whenever the PV power is not in access. Extensive simulation results using MATLAB-Simulink is presented to validate the proposed WPT topology and its multi-stage control system.

The LLC resonant converter, as a promising solution for battery charger applications, has the ability to adjust its output voltage during Constant Current and Constant Voltage modes in the charging profile. However, its operation mode changes as switching frequency changes. Therefore, for efficiency-oriented optimizations in battery charger applications, the one-pointed efficiency is not an appropriate objective. To this end, in this paper, a multi-pointed averaged efficiency is considered for optimization along with the transformer volume. Another factor of a proper design for a wide output range LLC is the converter peak voltage gain that is calculated based on an accurate method. The efficiency calculations are carried out by using time-domain-based analysis for every operation points. Regarding dead-time, a worst case is realized during the charging profile. At last, a 500W 400V:48V battery charger is designed with this procedure, and verified by simulation.

Multilevel Inverters (MIs) have great applications These days as one of best answer for medium and high power usages. The Five-Level Active-Neutral-Point-Clamped Inverter (FANPCI) merges the specifications of the typical flying-capacitor type and Neutral-Point-Clamped type inverter and was commercially used for industrial applications. In this paper, a new five-level five active switches and four diodes has been proposed, which employs only five active switches and four discrete diodes to produce all the five levels. Also, the modulation technique applied for the five-level five-switch NPC inverter has been discussed. Finally, a 4KVA single-phase prototype has simulated by using the PSPICE software to check the feasibility of the presented structure and control strategy.
