“…The equivalent circuit of the interleaved parallel mode is presented in Fig.4. Here, we take coupling transformer 1 T as the example to verify how the CT suppresses the generation of the circulating current. Considering a symmetrical structure without leakage flux, it is assumed that the self-inductance of each winding and the mutual-inductance between arbitrary two windings is equal respectively.…”

“…With the continuous improvement of power electronic devices in voltage and power levels in recent years, multi-level converters are widely used in the field with high voltage and high power [1,2]. Multilevel is generated in three-phase rectifiers to improve the power quality in high ac-dc converters, and the prevalent method in multi-level rectifiers is the neutral-point-clamped type [3,4].…”

This paper presents a three-phase interleaved parallel Vienna rectifier employing a coupling transformer. The application of coupling transformer figures out the current sharing problem between two parallel Vienna converters successfully, meanwhile, the volume of input EMC filters and passive components are reduced for the coupling transformers. The proposed rectifier also presents the inherent benefits: high power factor, higher power density, lower input current ripple and lower output voltage ripple. The operation of the PFC rectifier is described, including the design guidelines for the coupling transformer.

This paper gives a review of several emerging dc-de converter topologies that combine capacitor-based and inductive converters in single hybrid converter structures. It is shown that, compared to the conventional topologies, the hybrid buck converters allow for a drastic reduction of the inductive components while minimizing switching losses and improving the overall power processing efficiency. Therefore, the hybrid converters result in a higher power density. As examples, buck with merged capacitive divider, a two-phase interleaved buck, and a differential buck-based multi-output power module for mobile applications are shown. The presented converters have up to four times smaller inductor volume and, at the same time, about 12% lower losses.

“…Power factor correction (PFC) is a good method for providing an almost sinusoidal input current. The boost converter is the most popular topology for PFC applications due to its inherent current shaping ability [2]- [4]. However, with universal input, usually a 400 Vdc output voltage is required for the boost PFC.…”

Abstract-An improved buck power factor correction (PFC) converter topology is proposed in this paper. By adding an auxiliary switch and two diodes, the dead zones in ac input current of traditional buck PFC converter can be eliminated. An improved constant ON-time control is proposed and utilized in this improved buck PFC converter to force it that operates in critical conduction mode (CRM).With optimal control parameters, nearly unit power factor can be achieved and the input current harmonics can meet the IEC61000-3-2 class C standard within the universal input voltage range. Moreover, the efficiency of the proposed converter is not deteriorated compared to the conventional buck converter. Detailed theoretical analysis and optimal design considerations for the proposed converter are presented and verified by a 100-W labmade prototype.
