Power Converters for Energy Storage Applications
- Analysis and Design from Theory to Practice -

Power electronics and static power converters play significant role in industrial applications, power generation and transmission, home appliance, transportation, etc., etc. In most of the applications above mentioned, we are facing higher and higher demand for an energy storage device. Several different energy storage technologies are available today: flywheel, electrochemical double layer capacitors (EDLC), fuel-cells (FC) and electrochemical batteries. An energy storage cannot be directly connected to the power conversion system. An interface ac/dc or dc/dc power converter between the energy storage and the system is also required.
In the first part of the seminar we will discuss state of the art energy storage devices, their applications, design and sizing. In the second part of the seminar, we will discuss in deep details interface power converters such as dc/dc and ac/dc converters. The discussion will cover different topologies such as voltage and current source converters, multi cell and multi-level converters, isolated and non-isolated converters, full and partial power rated converters, etc., etc. Control strategy of different concepts will be covered too. Several case studies and design examples will be given as concluding part of the seminar.
This seminar is aimed at power electronics engineers, professionals and graduate students who want to improve their knowledge and understanding of advanced energy storage devices, interface converters and their application in power conversion, nowadays as well as in the near future.

MMC-based Converters for MVDC Applications

Medium Voltage Direct Current (MVDC) power distribution networks are currently being considered for various applications, from large wind and solar power collection and distribution grids to marine on-board electrical systems. Research activities in these areas also reveal various technological gaps, predominantly the lack of suitable conversion and protection equipment. In contrast to Solid State Transformers (SSTs), characterized with highly modular converter structures comprising multiple galvanically isolated sub-converter stages, there are other possibilities to realize high-power medium voltage isolated converters employing a single transformer for isolation. The Modular Multilevel Converter (MMC), with its excellent voltage scalability through series-connection of cells, offers such a possibility for various conversion structures needed in MV applications. This will be covered in the tutorial, predominantly focusing on high power MMC-based DC-AC and DC-DC galvanically isolated converters for MVDC applications. Topologies proposed in the literatures, as well as novel topologies proposed by authors, will be covered, analysed and supported by illustrative PLECS simulation examples.
