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

Cascaded AC-DC Power Conversion Interface for Charging Battery
Electronics, 2023 This paper develops a cascaded AC-DC power conversion interface (CADPCI) to convert AC power to charge the battery set. The proposed CADPCI is composed of a cascaded converter (CC) and a dual-input buck converter (DIBC). The CC is formed by connecting a full-bridge converter (FBC) and a bridgeless rectifier (BLR) in series.

A Single-Stage Direct-Conversion AC–DC Converter for Inductively Powered Application [PDF]
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2018 An innovative single-stage ac–dc converter for low power, low frequency skin depth wireless power transfer is presented. The power conversion efficiency (PCE) of a wireless power receiver is limited by the cascaded two-stage design, which constitutes a rectifier and a voltage regulator.
