A medium/high-frequency (MF/HF) transformer has become an integral part of many high-power conversion systems. Therefore, it is important to study the frequency response analysis (FRA) of a MF/HF transformer to ensure a reliable and safe converter operation. In this paper, frequency-dependent behavior of the transformer parasitics and their effects on the natural resonance frequencies are analyzed. A transfer function based π-model is employed to compute the frequency-dependent FRA of a two-winding transformer and estimate its natural resonance frequencies. It concludes that at high frequency, increased winding ac resistance exhibits higher damping effect at the resonance frequencies; whereas reduced leakage inductance shifts the resonance frequencies towards the high-frequency region of frequency response. Analytical calculations are verified with the help of experimental results obtained from a 1.5 kW, 15 kHz ferrite core transformer. The predicted and measured values of the resonance frequencies agree well, indicating a good modeling accuracy and aptness of the proposed methodology.

Digital average current-mode control (CMC) technique is popular in the power management industry due to its better noise immunity and the ability to track average current with high accuracy. A discrete-time framework for modeling and analysis of the inner current-loop of a digital average current-mode controlled buck converter is presented in this paper. A discrete-time 1-D model of the current loop is exploited for both fast-scale stability analysis and controller tuning of the inner current loop. The analysis shows that stable range of the proportional gain of the current loop PI controller is limited by the applied input voltage of the buck converter. An analytical expression of the stable range of proportional gain is derived from the proposed analysis. A buck converter prototype is developed and digital controllers are implemented in a 32-bit microcontroller (TMS320F28335 from Texas Instruments). Experimental results show a good agreement with the proposed analysis. The framework of this paper can be exploited to analyze the stability status of average CMC in other types of DC-DC converters.

Cascaded Z-Source topology coupled with a three-level diode clamped inverter provides an alternative multilevel buck-boost power conversion. Z-Source Inverter utilizes the shoot through states to conjoin the diode clamped inverter with one of the sources in the cascaded Z-Source topology. This unique integration during the shoot through states of the inverter facilitates the boosting of the three-level output voltage. In this paper, de-link voltage balancing of the cascaded topology when the input sources are non-identical is proposed. Reference disposition modulation method is utilized to couple the inverter to the Z-Source topology. The mathematical modelling of the cascaded impedance networks for the non-identical condition is derived in this paper. The circuit analysis proves that the de-link voltage balancing is attainable by carefully adjusting the duty cycle of the shoot through states. Subsequently, simulations results carried out in MATLAB/Simulink platforms validate the mathematical modelling of the cascaded Z-Source topology.

This paper presents the control and operation of single-phase chopper based five-level active neutral point clamped inverter (ANPCI) to reduce voltage ripple of DC-link capacitors. A capacitor voltage balancing algorithm is implemented to regulate the flying capacitor (FC) and DC-link capacitor voltages. As the voltage ripple of DC-link capacitors is significant, large DC-link capacitors are required to generate an acceptable five-level output voltage waveform. Hence, to reduce the voltage ripple and size of DC-link capacitors and FC, a chopper based ANPCI (CANPCI) is implemented with two control methods, viz., hysteresis current control and hysteresis voltage control methods. These control methods can also limit the maximum chopper inductor current as desired. The ANPCI and CANPCI are implemented in PSCAD/EMTDC simulation and hardware prototype along with the capacitor voltage balancing algorithm and their results are compared.

Constant power loads like electric traction load, lathe machines, grinding machines and coiler drivers are important assets to the industry. Considering that these constant power loads are coupled to motors which are connected to weak grids where voltage dips are frequent, this paper introduces a novel analysis of the effect on speed and torque of a synchronous reluctance motor connected to a constant power load on the occurrence of a voltage dip greater than the tolerable voltage dip margin for a particular operating point. The focus of this paper is to estimate the amount of reduction in speed as well as torque and changes in the other operating quantities from the set reference values if the dc bus voltage reduces below a pre specified permissible limit. Also the method of restoration of initial operating speed on the occurrence of a voltage dip is also discussed in this paper. The proposed analysis predicting the degree of changes in all the operating quantities is validated by simulations carried out in Simulink/MATLAB environment.

Battery recharging is an essential aspect of integration of Electric Vehicle (EVs) into the transportation framework. So far, charging stations have been considered as the primary source for recharging EVs. However, a significant time is is taken at the charging station to recharge a single EV. This problem is addressed by Battery Swapping Stations (BSS) that allow for swapping a depleted battery (DB) with a charged battery (CB). As with charging stations, the participating entities remain to be the grid, the aggregator, service station(s) and the EV owner. However, a variation exists in their interaction. In this work, a scheduling management scheme is presented for an aggregator to maximize its profit while managing BSS in a densely populated area. Furthermore, this has been explored for a varying number of requests. Furthermore, a PV assist has also been considered for BSS, where the depleted batteries may be charged through the PV assist. In both cases, with and without penalty for unscheduled EVs, in the case of no PV assist and with PV assist, results indicated that maximum profit was observed in the case of PV assist. Furthermore, more batteries were found to be available for swapping in the case with PV assist.

This study introduces a novel neural instantaneous power theory (Neural-IPT) based on a feed forward backpropagation artificial neural network (FFBP-ANN), for a three-phase shunt active power filter (SAPF) associated with a PV power plant. In order to check the performance of the proposed method of control, the studied system is subject to sudden disturbances caused at first by the variation of the ignition angle of the nonlinear load and then by an abrupt changes of the PV output parameters as well. Simulation outcome using MATLAB/Simulink tools, show that the proposed strategy of harmonics extraction, in conjunction with a Neural Network Hysteresis Controller, provides a quick and a precise estimation of the fundamental component of the nonlinear load, compared to the classical instantaneous power theory IPT, and consequently offers a best dynamic performance tracking, guarantee the imaginary power compensation and reduces source current distortion.

In modern power distribution system, standalone direct current (DC) microgrids are progressively explored. Important issues in DC microgrid operation are to ensure voltage regulation and proportional power sharing among sources. To solve these problems, comprehensive control scheme is presented for proportionate power sharing and better voltage regulation. A pivot element of this approach is formation of different power pools based on the accessible power from every renewable energy sources (RESs). In addition, it executes the coordinated operation of all power pools for effective power management. It is possible to make effective use of the energy storage systems (ESSs) by reducing their charging/discharging. Experimental studies prove the capabilities of the proposed scheme.

Simulation results verify the benefits and drawbacks of each clamping methods. An experimental prototype of BEHI converter is designed, built and tested by incorporating different clamping techniques using reconfigurable hardware structure. In this work, the experimental results of BEHI converter are verified using active clamp method around rated power of 5 kW with drastic reduction in transient voltage peak (less than 100V) and thereby achieved higher converter efficiency(~92%).

The voltage output at the terminals of a DC generating source such as Photovoltaic and Fuel cells is not enough to be integrated with the DC bus of a microgrid. Therefore, an efficient DC-DC converter is demanded for boosting the voltage. The available conventional converter needs to be operated at an extremely large duty ratio resulting in various detrimental effects on the converter circuit. Impaired transient response, increased EMI and voltage spikes are observed as a consequence of large duty ratio. High gain DC/DC converters are thus sought which must be attaining sufficiently high voltage on moderate duty ratio. This paper presents a novel converter utilizing two switches and switch inductors to come across the voltage suitable for integration of a renewable energy source into a DC microgrid. This particular converter does not uses transformers, coupled inductors, or some cascaded configurations. Moreover, the switches being controlled simultaneously do not need a complex control circuitry. The analysis of the introduced converter is done in CCM and DCM along with the boundary conditions. The performance is verified through simulation and experimental results.
