This paper presents an overview of thermal management solutions, in support of ship electrification, that are being investigated for power electronic building blocks and their integration into power corridors, both of which are seen as enablers of flexible and reconfigurable power distribution systems in the next generation Navy ships. Air, liquid, two-phase, and indirect cooling approaches are discussed in the context of specific building block configurations built and designed at CPES (Virginia Tech). The paper presents an overview of ongoing efforts towards the design, construction, and testing of cooling technology prototypes.

Hardware-Based Fault-Tolerant Technique for Modular Multilevel Converter Based on Shifting Submodules between Legs

Reliability is the major concern of megawatt power electronics technology is primarily concerned with reliability, and modular multilevel converter (MMC) is the ideal architecture for various medium-power and high-power applications. This research suggests a hardware-based solution for improving MMC's fault-tolerance. The proposed approach avoids unscheduled interruptions and raises the post-fault line voltage amplitude. This approach achieves maximum balanced line voltages by equalizing the number of functional SMs in the upper and lower legs and adjusting the neutral point location. The suggested strategy is defined for a generic fault situation, and the performance of the proposed method is validated by considering many fault states. The efficiency of the suggested method is shown by simulation results.

This paper proposes an approach for selecting an optimal placement and control variable setting by finding the worst contingencies for the recently proposed Interline Direct Current Power Flow Controller (IDC-PFC) in MultiTerminal High-Voltage DC (MT-HVDC) Grids based on Max Flow- Min Cut Theory. It is for Optimal PFCs’ placements that purposes to optimize the maximum capacities of the transmission grid. Optimal settings for finding the most critical HVDC lines in a meshed grid and deciding where to place the PFC afterward. The controllable Voltage Source Converters (VSC)s are computed by applying a sequential quadratic programming solver in MatLab to the developed security-based DC optimal power flow problem including several corrective constraints.

Using Grid Connected PUC Inverter With Robust Control Against Hybrid DG's Oscillation

In this paper, a packed U-cell inverter is used with predictive control in which uses hybrid distributed generators with output voltage oscillations. Since the converter is used in the grid-connected application, consequently low THD is needed in the point of common coupling (PCC). The distributed generators are different and each of them has considerable variations in their output terminal. So, using an improved configuration against these oscillation is necessary. Therefore, the PUC configuration is proposed for these applications. Distributed generators include fuel cell and PV that in the output terminal of each of them considerable oscillation could be generated.

This paper presents a new fully soft switching boost converter with one auxiliary switch that provides Zero Voltage Transition (ZVT) for the main switch in Continues Current Mode (CCM). The auxiliary circuit provides soft switching condition for both switches and all diodes in both turn on and turn off operation that can provide better efficiency and reliability for converter. Furthermore, reverse recovery problems of diodes and EMI noise of switches are alleviated. Simulation tests are conducted in PLECS software and results are included to verify theoretical analyses and feasibility of the proposed soft switching structure.

A modified soft-switched boost converter with a lower number of auxiliary components is proposed in this paper that provides either zero-voltage-transition (ZVT) or zero-current-transition (ZCT) operation for main switch and diode. Proposed converter is utilized in a single-phase grid-tied photovoltaic power generation system. Due to importance of maximum power harvesting from PV, incremental conductance MPPT procedure is employed to control DC/DC converter. Simulation is performed in PLECS software to validate the advantageous introduced soft-switching technique.

This paper presents a modified quasi Z-source inverter with a less number of switching devices. In a wide range of modulation index, the output voltage of the proposed inverter has a lower THD compared to Quasi-Z source cascade multilevel inverter (qZS-CMI). To illustrate the superior advantages of the proposed topology over the conventional qZS-CMI, both inverters are studied for the same condition. Various modulation indexes are considered and performance of both topologies are analyzed. By varying the modulation index in both inverters, different voltage amplitudes can be achieved. The obtained results from several simulations demonstrate the higher performance of the proposed topology with lower THD in the output voltage. The most important feature of the proposed topology can be mentioned as reducing the number of semiconductor devices, which leads to reducing the implementation cost of the …
