   Battery Inverter System for Stationary,1500 V Hybrid Battery Storage Applications
By Robert KRAGL, Cornelius ARMBRUSTER, Stefan REICHERT, Stephan LIESE, Akshay MAHAJAN [View]
[Download]

Abstract: Battery storage systems are crucial for the future energy infrastructure due to the fluctuating power generation of renewable energies. To increase the system efficiency and power density a trend toward higher battery and system voltages arises. Therefore, this paper introduces a demonstrator for the power electronics of a stationary, 1500 V hybrid battery storage system. A peak efficiency of 97.7 \% was measured for the system (DC/DC converter and inverter).

   Design and analysis of a voltage ride-through testing solution based on a novel medium-voltage OLTC auto-transformer
By Ramon LOPEZ-ERAUSKIN, Manex BARRENETXEA INARRA, Enrique SAGREDO BLANCO, Jose María CANALES SEGADE, Fernando SANTODOMINDO LLAMAS, Jose DUARTE [View]
[Download]

Abstract: In this paper, a novel medium-voltage autotransformer capable of generating under- and over-voltage conditions is introduced. The autotransformer could emulate grid disturbances at 20kV, 30kV and 35kV, satisfying the main grid code requirements applied to distributed generation systems.

   Performance Analysis of A New High Step-Up Boost-Buck-Boost Interleaved Converter for Bipolar LVDC Applications
By Babak ROOHOLAHI, Yam SIWAKOTI, Frede BLAABJERG, Hans-Günter ECKEL [View]
[Download]

Abstract: This paper presents a performance analysis of a novel single-input dual-output DC-DC converter for bipolar low-voltage DC (LVDC) distribution systems. The converter combines traditional boost and buck-boost converters using a shared inductor, providing voltage balancing and a common-ground condition. In particular, the focus of this study is on investigating the influence of the time-sharing factor (TSF) on the converter's performance. Through detailed theoretical analysis and PLECS simulation verification, the effects of varying the TSF values on key converter parameters, such as inductor current, voltage regulation, power losses and efficiency, are thoroughly discussed. The results presented in this paper contribute to the advancement of efficient and reliable power conversion techniques for emerging LVDC grid applications.
