ABSTRACT
  • The dc component can cause line-frequency power
    ripple, dc-link voltage ripple, and a further
    second-order harmonic in the ac current.
  • This paper has proposed an effective solution to
    minimize the dc component in three-phase ac
    currents and developed a software-based approach
    to mimic the blocking capacitors used for the dc
    component minimization, the so-called virtual
    capacitor.
  • The virtual capacitor is achieved by adding an
    integral of the dc component in the current
    feedback path.
  • A method for accurate extraction of the dc
    component based on double time integral, as a key
    to achieve the control, has been devised and
    approved effective even under grid-frequency
    variation and harmonic conditions.
