“…Bridgeless configurations, as mentioned in [13], can present an interleaved topology that offers better performance and reduces the size of the magnetic devices needed. Improved efficiency through the soft switching operation of all switching devices is analyzed in [14]. Here, a snubber circuit is integrated into an interleaved PFC converter.…”

In this paper, a Power Factor Correction (PFC) application, based on the novel power stage topology named Independent Double-Boost Interleaved Converter (IDBIC), has been analyzed. The novelty of the proposed PFC rectifier is based on the sum of capabilities, such as supplying three independent output voltage levels with interleaved operation at the input and high voltage gain. The hardware used within this application consists of an AC input L-C-L filter, a single-phase bridge rectifier, the IDBIC power stage, output capacitors group and a group of variable high-power rheostats (resistors) group as DC load. The main purpose of the carried study was to highlight the advantages and disadvantages of the novel power stage topology in the context of a green and modern AC to DC conversion solution. Nowadays, a high level of the efficiency and power factor have become a mandatory feature for the AC to DC conversion solutions to satisfy the international electrical standards. Thus, considering the modern electrical standards and recommendations, the current study tries to better depict the working steps and principles of the modern power stage topology within an AC to DC conversion application. The behavior of the considered power stage described in different detailed working steps (such as the Discontinuous Conduction Mode and Continuous Conduction Mode) may help understand how the energy conversions process of AC to DC becomes more efficient. The high output voltage gain of the considered power stage is the key feature in the Power Factor Correction process. With such a feature, the AC to DC conversion solution/application can also operate at lower input AC voltages (such as 90 [V] and 110 [V]). The proposed solution can be successfully used in the electric vehicle (automotive field) and high-power electrical traction (e.g., trains, high power electrical machines and drives). The same solution can also be used successfully in fast battery charging applications and chemical electrolysis processes.

“…Soft-switching methods for these converters can either be zero-voltage switching (ZVS) if they are implemented with MOSFETs or zero-current switching (ZCS) if implemented with IGBTs. The focus of the paper is on ZCS methods for IGBT converters [18][19][20], [22][23][24][25], [27][28][29][30][31][32][33][34]. Most of these, use an auxiliary circuit that is activated whenever a main converter switch is about to be turned off, gradually diverting current away from the switch so that it can turn off with ZCS.…”

An AC-DC Interleaved ZCS-PWM Boost Converter With Reduced Auxiliary Switch RMS Current Stress

et al. 2021

The paper proposes a novel interleaved AC-DC ZCS-PWM boost converter that requires the use of just a single active auxiliary switch to assist in the turning off the main power circuit switches with ZCS. The auxiliary switch can be turned on and off with ZCS and its auxiliary circuit allows the converter to operate without an increase in the main switch peak current or voltage stress. The auxiliary switch in the converter is active for a much shorter time than in most other ZCS-PWM converter, which allows the converter to operate at higher power levels than other previously proposed interleaved ZCS-PWM converter with a single auxiliary switch. The proposed converter's operation is explained in the paper and its key features and design considerations are discussed. Experimental results that confirm the operation of the proposed converter are presented as well.

“…As explained above, studies have been carried out for a high-efficiency PFC converter that utilizes the softswitching function with the critical mode control method and enables a small-sized input filter. With a design policy which enables enhancement of the power source current distortion suppression effects through interleave connection, in this paper, a soft-switching interleaved PFC converter with lossless snubber applied with improvement method of the power source current waveform is proposed, and effectiveness of the proposal is verified [15].…”

This paper describes a soft-switching interleaved power factor correction (PFC) converter with a lossless snubber. AC-DC converters require a unity input power factor characteristic with highly efficient operation to prevent the inflow of harmonic current to the power source. The proposed PFC converter improves the input current ripple with interleave control. The converter realizes a high efficiency by the soft-switching operation of all switching devices without a large auxiliary resonant circuit. This paper introduces the soft-switching operation of the converter. In order to confirm the validity of the proposed converter, experiments with a prototype of the PFC converter have been performed. The experimental results indicate that the proposed converter can realize the soft-switching operation of all switching devices, a reduction in the input current ripple, a unity power factor of 98% or more, a sinusoidal input current, and constant output voltage control. The efficiency of the proposed PFC converter with a lossless snubber is higher than that without the lossless snubber. The results presented in this paper confirm the validity of the proposed converter. C⃝
