For low-cost isolated ac/dc power converters adopting high-voltage dc-link, research efforts
focus on single-stage multilevel topologies. This paper proposes a new single-stage three …

The main objective of this research work is to develop a new low-cost isolated three-level ac–
dc power converter topology with a reduced number of switches. Existing three-level …

Quasi single-stage single-phase ac-dc power converters based on a three-port bridgeless
power factor corrector (TPB-PFC) are proposed in this paper. The TPB-PFC, which is able to …

A new interleaved three-phase PFC ac-dc single-stage multilevel is proposed in this paper.
The proposed converter can operate with reduced input current ripple and peak switch …

This article analyzes a three-phase single-stage isolated flyback-based power factor
correction converter and presents a novel clamping circuit to capture the transformers …

A single-stage bridgeless ac-dc PFC converter using a lossless passive snubber and valley
switching is proposed. The proposed converter is based on a two-stage bridgeless boost …

Future three-phase ac-dc converter systems ideally allow for bidirectional power flow,
provide high-frequency isolation, and feature buck-boost capability. Further, high efficiency …

For unidirectional power flow applications at the medium-voltage (MV) level, multilevel
converters with fewer active devices are cost-effective and more efficient than bidirectional …

A new isolated bridgeless PFC converter based on active-clamped SEPIC is proposed.
Compared to conventional active-clamped SEPIC PFC converter, the proposed converter …

Single-stage PFC AC/DC power converters promise lower cost and simplicity than two-stage
converters. This is especially important for low power converters. A new family of single …
