DOI: 10.1109/tpel.2024.3407207
Abstract: This article introduces a general interchanged interleaving scheme for multiparallel converters. Our analysis identifies a common challenge to the multiparallel converter using the existing interleaving scheme: the fixed interleaved angles introduce dc-bias/low-frequency intraphase and zero-sequence… read more here.
