Medium voltage (MV) power electronic transformers (PETs) are nowadays considered, for various industrial applications, as a viable replacement for bulky line-frequency operated transformers. In MV applications modularity in the converter design plays a ver ...
The paper describes the design of optimized printed circuit board (PCB) air-core toroids for high-frequency dc-dc converters with strict requirements in terms of volume and noise. The effect of several design parameters on the overall inductor volume, on d ...
A major change in the electrical transmission and distribution system is taking place in Europe at the moment. The shift from a centralised energy production to a distributed generation profoundly changes the behaviour of the grid. Environmental or social ...
his paper presents a multiport galvanically isolated LLC resonant DC-DC converter suitable for DC applications. A three-port structure is analyzed, with full bidirectional power flow capabilities, simple control and behavior similar to that expected from a ...
This paper provides detailed analytical modeling and finite elements method (FEM) analysis of the thermal behavior of the medium frequency transformer (MFT). A comprehensive analytical model in form of a thermal network consisting of conduction, convection ...
This paper provides detailed analytical modelling and finite elements method (FEM) analysis of the medium frequency transformer (MFT) leakage inductance, as one of the key design factors governing the operation of galvanically isolated power electronics co ...
Grid-tied inverters are the main responsible for the successful integration of photovoltaic (PV) plants in the power grid. Two important challenges are the integration of power plants based-inverters and their contribution to the power system quality. This ...
In the area of medium voltage DC-DC conversion, LLC Series Resonant Converter (LLC-SRC) presentsitself as an attractive topology for implementation of the DC transformer. Employing Integrated Gate Commutated Thyristor (IGCT) as a switching element one can ...
The main challenge of medium-frequency transformers is the number of design parameters, constraints and objectives, and the difficulty of handling them on a particular design. This paper presents a novel computer-aided optimal design for MF transformers us ...
A multiport medium voltage (MV) isolated DC-DC converter with integrated energy storage, suited for connection of low voltage (LV) and medium voltage (MV) DC grids is presented. A multi-stage structure, adapted for MV ratings, is composed of multiple ident ...
