Power Quality Improvement Using an Active Power Sharing Scheme in More Electric Aircraft

This article proposed a harmonic suppression scheme that used dc-dc converter as an active injector to cancel voltage harmonics on the HVdc bus within hybrid power generation centre (HPGC). A permanent magnet synchronous generator and battery are considered supply common through their dedicated ac-dc converters respectively HPGC. We simplified mathematical models of from converters. Thereafter, sharing between PMSG is developed control magnitudes targeted be same. The can thus cancelled by properly tuning carrier signal phase angles closed-loop has been this with no extra hardware cost. To demonstrate effectiveness scheme, we selected first-band ( fc ? 3 xmlns:xlink="http://www.w3.org/1999/xlink">f0 ) component. cancellation for component validated using experimental results. It demonstrated method achieve over 90% reduction specific HPGC one converter.
