Design of a Digital Offset Compensator Eliminating Transformer Magnetizing Current Offset of a Phase-Shift Full-Bridge Converter
IEEE Transactions on Power Electronics(2012)
摘要
A transformer magnetizing current offset for a phase-shift full-bridge (PSFB) converter is dealt with in this paper. A model of this current offset is derived and it is presented as a first-order system having a pole at a low frequency when the effects from the parasitic components and the switching transition are considered. A digital offset compensator eliminating this current offset is proposed...
