Abstract
A true unit-connected generator-HVdc convertor scheme is proposed whic h removes the need to use two bridges in series to achieve twelve-puls e operation. Moreover, the combination of a single main bridge and an auxiliary feedback dc ripple reinjection bridge is shown to increase t he pulse number from 6 to 18. This is achieved purely by natural commu tation and is equally valid for rectification and inversion. The theor etical waveforms are validated by extensive experimental verification.
