Efficiency and Cost Optimization of Dual Active Bridge Converter for 350kW DC Fast Chargers
Sadik Cinik, Fangzhou Zhao, Giuseppe De Falco +1
This study focuses on optimizing the design parameters of a Dual Active Bridge (DAB) converter for use in 350 kW DC fast chargers, emphasizing the balance between efficiency and co…
Low-frequency Resonances in Grid-Forming Converters: Causes and Damping Control
Fangzhou Zhao, Tianhua Zhu, Zejie Li +1
Grid-forming voltage-source converter (GFM-VSC) may experience low-frequency resonances, such as synchronous resonance (SR) and sub-synchronous resonance (SSR), in the output power…
Closed-Form Solutions for Grid-Forming Converters: A Design-Oriented Study
Fangzhou Zhao, Tianhua Zhu, Lennart Harnefors +5
This paper derives closed-form solutions for grid-forming converters with power synchronization control (PSC) by subtly simplifying and factorizing the complex closed-loop models.…
Efficacy Analysis of Power Swing Blocking and Out-of-Step Tripping Functions in Grid-Following VSC Systems
Yongxin Xiong, Heng Wu, Xiongfei Wang +1
Power flow oscillations can occur in power systems after major disturbances such as system faults, which may result in significant power swings and even lead to system collapse. Th…
