ABSTRACT
  • This project has presented a stability analysis
    of a LCL type grid-connected inverter in the
    discrete-time domain.
  • It has been found that even though the system is
    stable when the resonance frequency fr is higher
    than one-sixth of the sampling frequency (fs/6),
    an effective damping scheme is still required due
    to the potential influence of the grid impedance.
  • With a conventional proportional
    capacitor-current-feedback active damping (AD),
    the valid damping region is only up to fs/6.
  • This however is not sufficient in the design
    process for obtaining a high quality output
    current and the system can easily become unstable
    due to the resonance frequency shifting.
  • Considering the resonance frequency design rules
    of the LCL filter, this project proposes an
    improved capacitor-current-feedback AD method.
