Active Buck–Boost Inverter

IEEE Transactions on Industrial Electronics, 2014
The voltage range of a renewable energy source, such as the photovoltaic cell, is influenced by the environment, light, temperature, and so on. The power conditioning system should adapt to the wide input voltage and have buck-boost ability. Based on the structure of the “ac/ac unit,” this paper presents a novel active buck-boost inverter (ABI ...

Analysis of chaotic buck, boost and buck-boost converters through switching maps

PESC97. Record 28th Annual IEEE Power Electronics Specialists Conference. Formerly Power Conditioning Specialists Conference 1970-71. Power Processing and Electronic Specialists Conference 1972, 2002
This paper is concerned with the analysis and comparison of nonlinear phenomena in current and voltage controlled boost, buck and buck-boost DC/DC converters. The study is carried out by using three different discrete time maps: the stroboscopic map, the S-switching map and the A-switching map, which are obtained by different samplings of the state ...

Analysis and experimental study of the buck, boost and buck-boost inverters

30th Annual IEEE Power Electronics Specialists Conference. Record. (Cat. No.99CH36321), 2003
In this paper, the analysis and experimental study of three kinds of inverters are presented, beginning with the traditional full bridge buck inverter, followed by two different inverter approaches, the boost and buck boost ones. This last two converters have the property of produce an output voltage higher or lower than the input voltage additionally ...

Worst-Case Input Voltage in Buck, Boost and Buck-Boost converters

2019 International Semiconductor Conference (CAS), 2019
Due to the increasing demands and rigor required for the functioning of electronic circuits, modern simulators must allow for more complex analyzes. These can be very effective tools when the designer does not have enough physical time and wants to obtain a solution that meets the requirements of the project, because allow multiple checks in a short ...

A novel voltage-bucking/boosting converter: KY buck-boost converter

2008 IEEE International Conference on Industrial Technology, 2008
In this paper, a novel voltage-bucking/boosting converter, named as KY buck-boost converter (i.e. 2D converter) is presented herein. Unlike the traditional buck-boost converter, this converter possesses fast transient responses, similar to the behavior of the buck converter with synchronous rectification.

A novel buck/boost/buck-boost three-input DC/DC converter

IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011
In hybrid renewable power systems, the use of a multiple-input dc/dc converter (MIC) leads to simpler circuit and lower cost, compared to the conventional use of several single-input converters. This paper proposed a novel three-input buck/boost/buck-boost converter, which can be applied in all kinds of input voltage application.

Aalborg Inverter - A New Type of “Buck in Buck, Boost in Boost” Grid-Tied Inverter

IEEE Transactions on Power Electronics, 2015
This paper presents a new family of high efficiency dc/ac grid-tied inverter with a wide variation of input dc voltage. It is a “boost in boost, buck in buck” inverter, meaning that only one power stage works at high frequency in order to achieve minimum

Buck-boost impedance networks

2007 European Conference on Power Electronics and Applications, 2007
Most inverters designed to date can only perform either voltage-buck or boost operation with buck-boost mode usually attained by introducing additional active semiconductor devices and passive components to the inverters. Although effective, adding active switches will complicate the inverter control, and push up the overall system costs.

A new transformerless semi‐quadratic buck–boost converter based on combination of Cuk and traditional buck–boost converters

International Journal of Circuit Theory and Applications, 2022
AbstractIn this paper, a new transformerless buck–boost converter is proposed. This converter is based on combining two basic converters, including Cuk and traditional buck–boost converters, along with a voltage multiplier (VM) at the output side. The proposed semi‐quadratic buck–boost converter operates in continuous conduction mode (CCM) and provides

On the design of single-inductor double-output DC-DC buck, boost and buck-boost converters

2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008
Design methodologies for Single-Inductor Dual-Output (SIDO) DC-DC switching converters are presented. The suitable control of a double feedback loop enables the single inductor sharing between two outputs with low output voltages errors and limited load-regulation. The design methods to achieve SIDO converters with a wide input supply voltage range and
