Single‐phase multi‐level AC–DC power conversion interface
IET Power Electronics, 2016 This study proposes a single‐phase multi‐level AC–DC power conversion interface that is composed of a power factor correction stage and a buck power conversion stage. The power factor correction stage is configured using two power factor correctors (PFCs) connected in cascade.

Novel topology of ac–dc converter using direct power conversion
IET Power Electronics, 2012 This study proposes a novel topology of the ac-dc converter using direct power conversion that has a simple structure and achieves high efficiency. The proposed converter is derived by integrating the step-down ac chopper and the output-voltage doubler. The proposed converter provides direct ac-dc conversion and isolated dc output voltage without using
