   Design of a SiC based Triple Active Bridge cell for a multi-megawatt DC-DC converter
By Jose MANEIRO [View]
[Download]

Abstract: The paper describes the design methodology of a novel Triple Active Bridge cell used as the buildingblock for modular DC-DC converters. The intended application is for Medium Voltage Direct Currentgrids, such as the DC collector for offshore wind farms. The latest generation of SiC MOSFETsemiconductors is utilized to operate in the medium frequency range while optimizing the efficiency.The dimensioning of the main cell components, including semiconductors, transformer and DCcapacitors is presented. The cell mechanical integration and cooling are also addressed.

   LC-StatCom with Symmetrical I-V Characteristic - Power Loss Analysis
By Glen FARIVAR [View]
[Download]

Abstract: In this paper a comparative loss analysis between a cascaded H-bridge (CHB) low-capacitance staticcompensator (LC-StatCom) with symmetrical I-V characteristics and a conventional CHB StatCom ispresented. Effect of the capacitor voltage ripples on switching and conduction losses are determinedthrough theoretical analysis. Simulation-based analyses on a 350-VA three-cell CHB LC-StatComsystem are provided to confirm the theoretical predictions.

   Modelling and control of interlinking converters between AC and DC buses in grid-connected microgrids
By Marian LIBEROS [View]
[Download]

Abstract: This work develops the synchronous reference frame control of an interlinking converter between the DC and the AC bus of hybrid microgrids. The interlinking converter is based on two parallel connected inverters. A 3D Space Vector Modulator is proposed to avoid the presence of circulating currents between inverters.

   Systematic Separation of Electrical Power Systems for Hardware-in-the-Loop Simulation
By Axel KIFFE [View]
[Download]

Abstract: The increasing complexity of power grids makes hardware-in-the-loop simulations of electrical power systems more and more interesting for the industry. The simulation models are typically large. They often have to be split and used on several hardware platforms to allow efficient computations. Finding an appropriate position for splitting the simulation model requires expert knowledge about the electrical power system itself and about the functionality and limitations of the simulation hardware. In this paper, we present criteria that have to be taken into account when splitting an electrical power system model into subsystems. These criteria can serve as a basis for a systematic model splitting algorithm, which requires no special expert knowledge.
