“…Alguns sistemas de energia renovável possuem baixos níveis de tensão de saída (entre 10 V e 50 V), portanto, precisam utilizar conversores CC-CC de alto ganho [1]- [5] para adequar suas tensões de saída para níveis usuais. Por exemplo, para a conexão com a rede elétrica que possui níveis de 127 V e 220 V RMS a tensão de saída dos sistemas deve ser adaptada para aproximadamente 200 V (para redes de 127 V rms) ou 400 V (para 220 V rms).…”

“…Conversores que utilizam a técnica de interleaving permitem maior processamento de energia, pois dividem os esforços de corrente na entrada e, em alguns casos, reduzem a ondulação de corrente na fonte [4], [5] A solução proposta permite a soma das tensões de saída de dois conversores Boost-Flyback, ou seja, dois conversores não isolados, sem a ocorrência de curto entre os capacitores. …”

Resumo -Um conversor CC-CC não isolado de alto ganho é proposto nesse artigo, o qual é denominado Duplo-Boost-Flyback de Alto Ganho pelo fato de combinar dois conversores Boost-Flyback convencionais, conectados em paralelo na entrada e com saída flutuante. Essa nova topologia aumenta o ganho estático do conversor e reduz a ondulação da corrente de entrada. A topologia proposta é ideal para aplicações com fontes de alimentação com baixa tensão que precisam elevar consideravelmente a tensão para ser utilizada, como por exemplo, arranjos fotovoltaicos, células combustíveis e baterias. Este artigo apresenta princípio de operação, ganho estático, estratégia de controle e exemplo de projeto. A verificação experimental foi realizada a partir de um protótipo de 1 kW com tensão de entrada de 48 V e saída de 800 V, alcançando o ganho estático de 16,7. A eficiência máxima apresentada foi de 94,6% com 70% da carga e 93,9% com carga nominal.Palavras-Chave -Boost-Flyback, Conversor de Alto Ganho, Conversor CC-CC, Energia Renovável, Indutor Acoplado. HIGH GAIN DOUBLE BOOST-FLYBACK CONVERTERAbstract -A high gain step-up non-isolated dc-dc converter is proposed in this paper, named as high stepup Double Boost-Flyback, the topology combines two conventional Boost-Flyback converters in input-parallel and floating-output connections. The new topology increases the static gain and reduces the input current ripple in relation to the conventional Boost-Flyback topology. The proposed converter has potential to be used in low input voltage applications that requires a high gain as such as systems powered by photovoltaic panels, fuel cells and low voltage batteries. This paper presents principle of operation, static gain, control strategy, and design example. The experimental verification was carried out in a prototype of 1 kW with input and output voltage of 48 V and 800 V, respectively, reaching a static gain of 16.67. A maximum efficiency of 94.6% was achieved at 70% of load and 93.9% at rated load. A diversificação da matriz energética mundial tem crescido com o uso de energias renováveis como, por exemplo: painéis solares, geradores eólicos, energia maremotriz, geotérmica entre outras.

Além disso, os níveis de tensão reduzidos na entrada fazem com que esses conversores operem com correntes elevadas, o que aumentam as perdas de comutação e de condução e, consequentemente, degradam a eficiência do sistema. Ganhos elevados e alta eficiência são os principais desafios dos conversores CC-CC.Os conversores mais comuns utilizados para essas aplicações são o Boost clássico [6]

“…Many of these sources operate with low voltage levels, i.e. from 10 to 50 V. Therefore, it is common to use a high‐gain dc–dc converter [1–5] to allow either connection to the utility grid or even an isolated application powering a conventional load. It is well known that a conventional utility grid operates with voltage levels from 110 to 230 V (RMS) .…”

“…On the other hand, interleaving techniques allow greater power processing in converters, because they divide the current stresses at the input and this reduces the current ripple drained from the source [4, 5]. As for disadvantages, they involve large amounts of components, which increase the cost, and they do not provide extra gain.…”

A high-gain step-up non-isolated dc-dc converter is proposed in this study, named the double boost-flyback converter. The topology combines two conventional boost-flyback converters with input-parallel and floating-output connections. The new topology increases the static gain and reduces the input current ripple in relation to the conventional boost-flyback topology. The proposed converter has the potential to be used in low input voltage applications that require a high gain, such as systems powered by photovoltaic panels, fuel cells, electric vehicles, and low voltage batteries. This study provides details on the principle of operation, static gain, control strategy, design guide and experimental verification. A 1 kW prototype was designed and built for an input voltage of 48 V and an output voltage of 800 V, reaching a static gain of 16.67. The maximum efficiencies obtained were 94.6% at 70% of load and 93.9% at rated load.

“…The basic aims of improving PF are to reduce greenhouse gas emissions and the electricity bills of consumers, to avail additional kilovolt-ampere from existing supply, and to extend equipment life. References [1]- [4] developed a PF correction circuit with supply current total harmonic distortion (THD) under the IEEE-519 limit, but they failed to concentrate on fluctuations in DC-link voltage and current. The active damping technique using a DC-link capacitor [5] seems to be simple and effective for regulating DC-link oscillations, but shortcomings occur when the load on the motor changes and can result in under or over correction; this technique is unsuitable for adjustable-speed drives.…”

An active front end (AFE) is required for a three-phase induction motor (IM) fed by a voltage source inverter (VSI), because of the increasing need to derive quality current from the utility end without sacrificing the power factor (PF). This study investigates a proportional-plus-integral (PI) controller based AFE topology that uses a super-lift converter (SLC). The significance of the proposed SLC, which converts rectified AC supply to geometrically proceed ripple-free DC supply, is explained. Variations in several power quality parameters in the intended IM drive for 0% and 100% loading conditions are demonstrated. A simulation is conducted by using MATLAB/Simulink software, and a prototype is built with a field programmable gate array (FPGA) Spartan-6 processor. Simulation results are correlated with the experimental results obtained from a 0.5 HP IM drive prototype with speed feedback and a voltage/frequency (V/f) control strategy. The proposed AFE topology using SLC is suitable for three-phase IM drives, considering the supply end PF, the DC-link voltage and current, the total harmonic distortion (THD) in supply current, and the speed response of IM.
