Optimization and Comparative Evaluation of Multiloop Control Schemes for Controllable AC Sources with Two-Stage LC Output Filters
(2016)IEEE Transactions on Power ElectronicsThis study investigates the control system design and its small-signal properties for the output stage of a high-bandwidth four-quadrant three-phase switch-mode controllable AC voltage source (CVS) with an output power of 10 kW, a switching frequency of 48 kHz, and a two-stage LC output filter. Each output phase of the CVS is operated individually, i.e., the phase voltages are generated with reference to the DC input-voltage midpoint, to ...Journal Article -
High-Bandwidth High-Temperature (250 °C/500 °F) Isolated DC and AC Current Measurement: Bidirectionally Saturated Current Transformer
(2013)IEEE Transactions on Power ElectronicsIn an increasing number of application areas and industry sectors, such as the automotive, aerospace, military or oil and gas industry, a trend towards higher ambient temperature rating from 85 °C upwards for electrical machines and power electronic converters can be observed. To reduce the impact of high ambient temperatures on the power density, the interest in power electronic converters with SiC power semiconductors operated up to a ...Journal Article -

An Isolated Three-Port Bidirectional DC-DC Converter With Decoupled Power Flow Management
(2008)IEEE Transactions on Power ElectronicsAn isolated three-port bidirectional dc-dc converter composed of three full-bridge cells and a high-frequency transformer is proposed in this paper. Besides the phase shift control managing the power flow between the ports, utilization of the duty cycle control for optimizing the system behavior is discussed and the control laws ensuring the minimum overall system losses are studied. Furthermore, the dynamic analysis and associated control ...Journal Article -
EMI Filter Design for the Integrated Dual Three-Phase Active Bridge (D3AB) PFC Rectifier
(2022)IEEE Transactions on Power ElectronicsA dual three-phase active bridge (D3AB) power factor correction (PFC) rectifier features two dc ports, i.e., one on the primary side, which is not isolated from the mains, and the second, which is galvanically isolated dc port on the secondary side. A model for calculating the conducted electromagnetic interference (EMI) noise of a 7.5-kW D3AB PFC rectifier operating from a 400 V rms line-to-line mains and generating dc output voltages ...Journal Article -
Geometrical Optimization of Medium-Frequency Air-Core Transformers for DCX Applications
(2022)IEEE Journal of Emerging and Selected Topics in Power ElectronicsThis article analyzes the potential of air-core transformers (ACTs) for realizing medium-voltage high-power isolated dc-dc converters. ACTs, i.e., transformers without magnetic cores, are particularly interesting for their simple construction and reduced weight. However, the reduced magnetizing inductance, the reduced magnetic coupling, and the stray fields are challenging aspects for the design of ACTs. A comprehensive model of the ACT ...Journal Article -
CFD Assisted Evaluation of in Vitro Experiments on Bearingless Blood Pumps
(2021)IEEE Transactions on Biomedical EngineeringObjective: This paper presents a comparative study of computational fluid dynamics (CFD) simulations and in vitro hemolysis examinations of a bearingless centrifugal blood pump. The outcomes of the in vitro study are analyzed with the help of CFD hemolysis models. Methods: Several pump prototypes were manufactured and tested. Each model was implemented in a CFD framework and simulated with different Eulerian hemolysis models. The outcomes ...Journal Article
