Abstract

This paper presents an in-depth analysis of the classic Z-source topology for DC power system protection, an area previously unexplored in such detail. Using OpenModelica simulations, the study offers valuable insights into the Z-source topology’s behavior, protection mechanisms, and energy dissipation processes. It includes detailed diagrams, switching states, and explanations of operating principles, supported by waveforms illustrating energy flow through the Z-source components. The findings demonstrate that the Z-source breaker effectively handles fault conditions by disconnecting the source from the load almost instantaneously, within tens of microseconds. The simulations confirm the theoretical models, showing that the Z-source topology efficiently dissipates fault energy through inductors, capacitors, and resistors, thereby protecting sensitive equipment. This thorough analysis enhances understanding of the Z-source topology in DC power systems and establishes a solid foundation for future research and practical applications.
