Abstract：

In　order　to　reduce　the　low-frequency　output　voltage　ripple　of　the　bridgeless　dual　Boost　PFC　converter,　a　boost-type　bidirectional　dc/dc　power　decoupling　circuit　is　used,　the　circuit　working　principle　is　analyzed.　A　model　predictive　current　control(MPCC)　controller　is　adopted　to　control　the　inductor　current　of　the　power　decoupling　circuit,　the　MPCC　is　improved　to　reduce　the　error　caused　by　digital　control　precision.　A　1000W　simulation　experiment　is　carried　out,　the　theoretical　analysis　is　verified,　the　inherent　ripple　power　in　the　ac　grid　source　is　transferred　to　the　power　decoupling　branch.　©　2019　IEEE.
