High step-up single-stage boost inverter

2011 IEEE Energy Conversion Congress and Exposition, 2011
This paper presents a high step-up single-stage boost inverter. The basic topology is known in the literature as a Z-source inverter (ZSI). The ZSI has the ability of buck-boost conversion. No dead time is needed in phase legs, so high reliability can be achieved.

Single-Stage Boost Inverter With Coupled Inductor

IEEE Transactions on Power Electronics, 2012
Renewable power systems as distributed generation units often experience big changes in the inverter input voltage due to fluctuations of energy resources. Often, a front-end boost converter is added to step up the dc voltage when the energy resources are at a weak point.

A Single-Stage Square Wave Buck-Boost Inverter

Applied Mechanics and Materials, 2015
This paper proposed a novel single-stage square wave buck-boost inverter (SWBBI). The proposed inverter is designed by using dual buck-boost converters. The input DC voltage of the proposed inverter can be either stepped-down or stepped-up in square output voltage waveform depending on the duty-cycle applied for each buck-boost converter.

A Novel Single-Stage Full-Bridge Buck-Boost Inverter

IEEE Transactions on Power Electronics, 2003
A novel single-stage full-bridge series-resonant buck-boost inverter (FB-SRBBI) is proposed in this paper. The proposed inverter only includes a full-bridge topology and a LC resonant tank without auxiliary switches. The output voltage of the proposed inverter can be larger or lower than the dc input voltage, depending on the instantaneous duty-cycle ...
