A comparison between the buck, boost and buck-boost inverters

7th IEEE International Power Electronics Congress. Technical Proceedings. CIEP 2000 (Cat. No.00TH8529), 2002
In 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 ...

Dual buck-boost inverter

2017 IEEE Applied Power Electronics Conference and Exposition (APEC), 2017
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.

Bidirectional buck-boost cascade inverter

2015 International Conference on Technological Advancements in Power and Energy (TAP Energy), 2015
This paper presents modelling and closed loop control of bidirectional buck boost cascade inverter, which produces an ac output voltage larger than the dc input voltage. The bidirectional inverter is seen as the cascade of a buck stage and a boost stage. The function of buck stage is to maintain main inductor current as a constant value and boost stage

New High-Gain Non-Inverting Buck-Boost Converter

IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021
This paper is presenting a new high-gain non-inverting buck-boost converter. The proposed converter has some distinct features such as high step up/down ability, low voltage and current stress on its switching devices. The voltage gain of the proposed converter is double of the traditional buck-boost converter and it is non-inverting.

Pulse Energy Modulation of a buck-boost inverter

2011 IEEE Energy Conversion Congress and Exposition, 2011
This paper presents an energy-based modulation approach for a buck-boost inverter. Pulse Energy Modulation (PEM) is proposed as a new approach to generate inverter switching pulses based on the desired output energy. The energy demand is calculated from the output voltage and reference current and the modulation index of the inverter is calculated ...
