Switched capacitor boost inverter
2016 IEEE 25th International Symposium on Industrial Electronics (ISIE), 2016The differential boost inverter (DBI) generates an alternating differential voltage from two dc-dc converters. The instantaneous output voltage can be higher or lower than the dc input voltage, however DBIs exhibit nonlinear control-to-output behavior in large-signal sense.

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 ...

Boosting static pruning of inverted files
Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval, 2007This paper revisits the static term-based pruning technique presented in Carmel et al., SIGIR 2001 for ad-hoc retrieval, addressing different issues concerning its algorithmic design not yet taken into account. Although the original technique is able to retain precision when a considerable part of the inverted file is removed, we show that it is ...

Extended-Boost $Z$-Source Inverters
IEEE Transactions on Power Electronics, 2009The Z-source inverter has gained popularity as a single-stage buck-boost inverter topology among many researchers. However, its boosting capability could be limited, and therefore, it may not be suitable for some applications requiring very high boost demand of cascading other dc-dc boost converters.

Inverter is a definitive solution toward ac voltage regulation in a system having input dc voltage variation. This paper proposes, a novel single-stage single-phase buck-boost inverter called dual buck-boost inverter. It has the buck-boost function and requires only four active switches. It has no shoot-through worries and has improved reliability.

Improved switching boost inverter
2016 IEEE 11th Conference on Industrial Electronics and Applications (ICIEA), 2016Z source inverter overcomes the shortcomings of the traditional voltage source and current source, but its DC side current is not continuous, the voltage utilization is low and the boost factor is limited. In recent years, some scholars have proposed a new inverter — switching boost inverter (SBI).

A comparison between the buck, boost and buck-boost inverters
7th IEEE International Power Electronics Congress. Technical Proceedings. CIEP 2000 (Cat. No.00TH8529), 2002In this paper, an 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. These last two converters have the property of producing an output voltage higher or lower than the input voltage ...

A boost-switched capacitor-inverter with a multilevel waveform
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004Two structures, a switched-capacitor (SC)-based boost converter and a two-level inverter, are connected in cascade. The DC multilevel voltage of the first stage becomes the input voltage of the classical inverter, resulting in a staircase waveform for the inverter output voltage. Such a multilevel waveform is closed to a sinusoid, its harmonics content

Analysis and PWM Control of Switched Boost Inverter
IEEE Transactions on Industrial Electronics, 2013The Z-source inverter (ZSI) employs an LC impedance network between the main inverter bridge and the power source. The unique feature of the ZSI is that it can operate either in buck or boost mode with a wide range of obtainable output voltages from a given input voltage.

Dynamical Sliding-Mode Control of the Boost Inverter
IEEE Transactions on Industrial Electronics, 2009The boost inverter is a device that is able to generate a sinusoidal voltage with an amplitude larger than the input voltage. Based on the idea of indirectly controlling the output voltage through the inductor current, a dynamical sliding-mode controller for the boost inverter is proposed in this paper.
