A Single-Stage Direct-Conversion AC–DC Converter for Inductively Powered Application [PDF]

open access: yesIEEE 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.

Single Power-conversion AC-DC Converter with High Power Factor

open access: yesThe Transactions of the Korean Institute of Power Electronics, 2014
This paper proposes a single power-conversion ac-dc converter with a dc-link capacitor-less and high power factor. The proposed converter is derived by integrating a full-bridge diode rectifier and a series-resonant active-clamp dc-dc converter. To obtain a high power factor without a power factor correction circuit, this paper proposes a suitable ...
