Single Power-Conversion AC--DC Converter With High Power Factor and High Efficiency

IEEE Transactions on Power Electronics, 2014
This paper proposes a single power-conversion ac-dc converter with high power factor and high efficiency. 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 novel control ...

High-Efficiency Soft-Switching AC–DC Converter With Single-Power-Conversion Method

IEEE Transactions on Industrial Electronics, 2017
This paper presents a high-efficiency isolated ac–dc converter topology. The proposed converter consists of a full-bridge diode rectifier, an isolated resonant dc–dc converter, and only one controller. The proposed converter provides the soft-switching technique for all components operating at high frequency, allowing for an improvement in power ...

Multilevel reduced controlled switches AC-DC power conversion cells

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
This paper presents multilevel ac–dc single-phase power conversion cells for applications in which the regenerative operation is either not required or prohibited. The ac primary power source is a single phase from a permanent magnet generator or from an electrical grid.

A Novel Three-Stage Power Electronic Transformer for AC/DC Conversion

2019 IEEE 28th International Symposium on Industrial Electronics (ISIE), 2019
In this paper, a novel three-stage power electronic transformer (PET) is proposed for AC/DC conversion. Compared with the existing PET topologies, the feature of the proposed PET is the decreased number of the power conversion stages. The mixed-frequency synchronous control strategy is also presented, which fulfills unity power factor (UPF) at the AC ...

Study of AC-DC converters with isolated transformers applied to high frequency AC-DC power conversion

2015 6th International Conference on Power Electronics Systems and Applications (PESA), 2015
At high frequency, such as 50 kHz, the behaviors of isolated transformers and diodes in rectifiers are considerably different from ones at low frequency, such as 50 Hz. The analysis and the experiment in this paper show that it suffers from poor power factor and low power output if conventional AC-DC converters with isolated transformer are directly ...
