Sparse AC-Link Buck–Boost Inverter

IEEE Transactions on Power Electronics, 2014
Due to their remarkable merits, the soft-switching ac-link universal power converters have received noticeable attention during the last few years. These converters, which can be configured as dc-dc, dc-ac, ac-dc, or ac-ac, are compact, reliable, and offer longer life time compared to the other types of converters.

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 ...

Novel Transformerless Buck–Boost Inverters Without Leakage Current

IEEE Transactions on Industrial Electronics, 2020
This article presents novel transformerless single-stage buck-boost inverters with reactive power flow capability. The common-mode voltage of the proposed inverters is constant, which results in negligible leakage current. The output current of the proposed inverters is continuous that lowers the output harmonics and size of the output filtering ...

A Novel One Stage Buck-Boost Inverter

2019 IEEE International Conference on Intelligent Techniques in Control, Optimization and Signal Processing (INCOS), 2019
This paper proposes a Novel One Stage Buck Boost DC-AC Inverter (OSBBDAI) which boosts and inverts the input DC into AC. Generally for an application, where an AC output is generated from low voltage DC, two stage converters are used – a front end DC-DC boost converter followed by a DC-AC Inverter. But in proposed topology the conversion is possible in

Non-inverting buck-boost converter for fuel cell applications

2008 34th Annual Conference of IEEE Industrial Electronics, 2008
Fuel cell DC/DC converters often have to be able to both step-up and step-down the input voltage, and provide a high efficiency in the whole range of output power. Conventional negative output buck-boost and non-inverting buck-boost converters provide both step-up and step-down characteristics.

Modelling and controller design for a non-inverting buck-boost chopper

Proceedings of the 2011 International Conference on Electrical Engineering and Informatics, 2011
Due to its simplicity, low voltage stress, high reliability, low switch and inductor losses, and small inductor size, the non-inverting buck-boost chopper has found a lot of attentions in applications where it is necessary to step-up or step-down the DC voltage.
