In order to facilitate the further integration of distributed renewable generation into existing power systems, enhanced control schemes for grid-tied power electronic converters are necessary to ensure non-synchronous power sources can provide power and support to the grid. The virtual-synchronous-machine concept proposes the use of control schemes to enable static generators to operate with the dynamics of rotating synchronous generators. In this paper, a control scheme is presented based on the principle of active-power synchronization to regulate the active power of a grid-tied voltage-source converter based on an emulation of the synchronous-machine swing equation. Design of a cascaded inner-loop voltage and resonant current control is presented to regulate the output voltage as specified via the outer-loop virtual-machine control scheme responsible for power regulation. The performance of this control scheme is investigated within the context of microgrid operation for the provision of active and reactive power to the system, and microgrid frequency support. Experimental validation is provided via the use of a 15 kVA three-phase VSC in a 90 kVA 400V microgrid.

In this paper, a new method for Space Vector Modulation (SVM) for the 3×3 direct matrix converter is proposed. This method is based on a combination of Model Predictive Control (MPC) and SVM, also denoted as Continuous Control Set MPC. The proposed method uses all available vectors, and allows the converter to produce waveforms of high quality at both power ports, also when subjected to unbalanced or distorted waveforms. The mathematical derivation of the proposed method is explained, and the operation illustrated by means of simulation experiments in open loop. The paper finishes with conclusions and prospects for further development and application of the method.

This paper presents the design, manufacture and characterization of connector-less 1200 V SiC MOSFET half-bridge power modules based on AlN DCB substrate. The modules contain four MOSFETs and no external antiparallel diodes. They are rated for a current of 40 A and include a shunt. Static and dynamic measurement results are presented. Multiphysics simulations are used to validate the measured data. The modules show a power path inductance below 3 nH. The power rating of the implemented chip shunt resistors is sufficient for the performed characterizations but requires revision. The switching loss at turn-on is 340 μJ at 23 A, 800 V, the turn-off loss is well below 50 μJ, principally allowing MHz operation in resonant mode.

The power coordination in DC microgrids has a vital role in enhancing the performance and management of multi generation units. Renewable Energy Sources (RES) are limited to their available power with intermittent nature. Battery-based energy storage sources have limitations in the charging and discharging capabilities to avoid depleting the battery and preserve the State of Charge (SOC) within its satisfactory limits. The battery balances the power difference between RES and loads. However, in severe cases where the SOC is very low, load shedding is crucial. In this paper, a Fuzzy Logic Controller (FLC) has been proposed to coordinate the power flow of PV unit and battery to satisfy the load by full use of the available PV power. It controls the PV's output power and keeps the SOC and charging / discharging power of the battery within their required margins regardless of the variations in load. Furthermore, load shedding of low priority load has been implemented when the battery couldn't balance the microgrid power flow. Simplicity in managing multi input-multi output system by FLC is the main merit. Matlab/Simulink results are presented to validate the performance of the proposed controller.

A three-phase dual active bridge (DAB) converter with three-level phase-legs is analyzed, showing an increased soft-switching region and a reduction in rms current in the ac-link for unequal input and output voltages compared to the conventional two-level circuit. Furthermore, a comparison of the semiconductor losses is carried out for different three-level inverter implementations using commercially available silicon (Si) and silicon-carbide (SiC) power modules. The lowest losses are found for the T-type implementation with a combination of SiC and Si power modules. Experimental results, obtained from a high-power prototype, are included to support the evaluation of the three-level three-phase DAB.

Resonant converters find widespread application in the industries for Radio Frequency (RF) heating. Various topologies using vacuum tubes are currently used for such application. Realizing class D topologies with solid state devices could provide more reliability. This work explores possibility of developing a 1kW Class D resonant converter for heating applications using Si/SiC MOSFETs which can replace vacuum tube RF generators. A resonant gate driver which enables efficient switching and modularity along with some practical aspects in implementing a class D converter is discussed here. The results from the developed class D converter and the suggestions for improvement are also highlighted here.

This paper explains a procedure on how to select resonant circuit components of a unique direct three-phase to single-phase AC/AC converter for a contactless electric vehicle (EV) charger. The topology has a fewer bi-directional switches than a matrix converter and consists of a resonant circuit to utilize a zero-current switching (ZCS) mechanism. The selection goal was to realize a working prototype that does not violate each electrical component's limitations as well as has a low resonant damping ratio since the switches are driven based on a resonant current. Selection methods were based on graphical analysis of damping factor, resonant frequency, and primary circuit voltage and current characteristics derived from dynamic and steady-state models. Simulation results are then presented to validate the selection procedures.

Electric Vehicles demand high efficiency power converter in their powertrains in order to use the energy of the storage unit in a better way. Specifically, the power converters, that interface the storage unit with the motors, are usually composed of high-losses components. Moreover, the topologies used in these systems present conditions of hard switching and reverse recovery phenomena that reduce the total efficiency in the vehicle. This work analyzes the recovery-less boost converter that can achieve Zero-Current Switching, reverse-recovery reduction and softening of the switching transition. Due to the technique of using two saturable inductors. In addition, the use of next-generation magnetic materials for increasing the efficiency and reducing the reverse recovery current is studied. In this paper, the circuit configuration, the operating principle and the reverse-recovery reduction of the recovery-less converter is reviewed. Moreover, the comparison of ferrites and nanocrystalline soft magnetic materials is presented. Finally, the effectiveness of the proposed comparison is validated by experimental tests. As a result, reduction of the peak recovery current and increase of the efficiency are confirmed, achieving a 71% of reduction of the recovery current and 0.25% of efficiency increase at 1kW of output power.
