Balancing Control Actions for Cascaded H-Bridge Converters with Integrated Battery Energy Storage

Alfred Rufer, Michail Vasiladiotis

This paper investigates the ways to handle active power components for control and balancing purposes in three-phase Cascaded H-Bridge converters with embedded battery energy storage systems. The split storage elements are interfaced to the converter modul ...

Sizing of branch inductors parameters in modular multilevel converters: An analytical approach

Alfred Rufer, Michail Vasiladiotis, Nicolas Cherix

One of the key features of Modular Multilevel Converters is the existence of inductors inside the branches that constitute each of their phases. These inductors, which may be coupled or non-coupled, authorize a certain independency in the control of the br ...

Fictive Axis Emulator-based State Feedback Vector Current Control for Single-Phase Voltage Source Converters

Alfred Rufer, Michail Vasiladiotis

This paper presents a vector current control method tailored for single-phase voltage source converters. In order to imitate the behavior of a three-phase system, the Fictive Axis Emulation (FAE) concept is employed. The latter is able to synthesize the ro ...

Modular Converter Architecture for Medium Voltage Ultra Fast EV Charging Stations: Global System Considerations

Alfred Rufer, Michail Vasiladiotis, Antoine Béguin

Electric Vehicles (EVs) are expected to contribute significantly to the reduction of CO2 emissions and other types of pollution within the next years. However, the concept of their ultra fast charging still poses demanding requirements, both in terms of th ...

Toward Ultrafast Charging of Electric Vehicles

Alfred Rufer, Hans Björn Püttgen, Massimiliano Capezzali, Michail Vasiladiotis, Hardi Hõimoja, Stefano Grioni

The paper is devoted to the problems arising from the ultrafast (≤ 10 min) charging of an electric vehicle (EV). An ultrafast charging station (UFCS) must provide high power output with minimal influence on the electricity transmission system, which can on ...

Accurate Voltage Ripple Estimation and Decoupled Current Control for Modular Multilevel Converters

Alfred Rufer, Michail Vasiladiotis, Nicolas Cherix

The analytical solution for the sub-module voltage ripple equations of a Modular Multilevel Converter (MMC) is derived, based on the knowledge of the external voltage/current magnitudes and enhancing a concept previously presented in literature. In order t ...

Functional Modeling and Energetic Macroscopic Representation of Modular Multilevel Converters

Alfred Rufer, Michail Vasiladiotis, Nicolas Cherix

A key feature of Modular Multilevel Converters (MMC) is the continuous and independent nature of the branch currents. Therefore, a decoupled control of the line and partial bus currents is possible, unlike for classical topologies. To this end, several con ...

Power and DC Link Voltage Control Considerations for Indirect AC/AC Modular Multilevel Converters

Alfred Rufer, Stephan Kenzelmann, Michail Vasiladiotis, Nicolas Cherix

A highly interesting application field of the Modular Multilevel Converter is the interconnection of the European three-phase 50 Hz industrial grid with the single-phase 16 2/3 Hz railway supply. Contrary to existing technologies, the utilization of a bulk ...

A Versatile DC-DC Converter for Energy Collection and Distribution using the Modular Multilevel Converter

Alfred Rufer, Drazen Dujic, Stephan Kenzelmann, Michail Vasiladiotis

The drawbacks of conventional Modular Multilevel Converters (MMC) are described in terms of short-circuits. The configuration of MMC-transformer-MMC proves to handle short-circuits at the input and output without the need for additional DC or AC circuit br ...
