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…
Gain and Phase: Decentralized Stability Conditions for Power Electronics-Dominated Power Systems
Linbin Huang, Dan Wang, Xiongfei Wang +4
This paper proposes decentralized stability conditions for multi-converter systems based on the combination of the small gain theorem and the small phase theorem. Instead of direct…
