“…Among its various topologies, the best suited DC-DC converter is opted by properly analysing their pros and cons. Table 1 comprehensively compares its different topologies such as buck converter [26], boost converter [26], buck-boost converter [11,26], Cuk converter [26,27], single ended primary inductor converter (SEPIC) [26], zeta converter [9,26], Luo converter [28] and canonical switching cell (CSC) converter [29], in terms of their MPPT operating region, quality of input and output currents and gate-drive circuitry. Table 1 also distinctly indicates that a Cuk converter qualifies in every aspect and hence it is adopted in this work.…”

A solar photovoltaic (SPV) powered brushless DC (BLDC) motor drive for water pumping is presented in this study. The current sensors of BLDC motor and the voltage sensor at the DC bus of voltage-source inverter (VSI) are eliminated completely. Instead, the speed is controlled by adjusting the DC bus voltage of VSI. The fundamental frequency switching pulses are generated to operate the VSI in order to minimise the switching losses and to enhance the efficiency of proposed system. A DC-DC Cuk converter is utilised to operate the SPV array at its maximum power. The starting current of BLDC motor is bounded by an optimal initialisation and selection of the control parameters, perturbation size and frequency while tracking the peak power of SPV array. The performance of proposed BLDC motor drive is thoroughly evaluated and its potential is demonstrated under realistic operating conditions. The simulated results and an experimental validation along with a comprehensive comparison with the existing techniques demonstrate prominence of the proposed drive for SPV-based water pumping.

“…The duty cycle for dc-dc converters are generated by considering the maximum power point operation of the converters. The extract maximum solar power from PV panels MPPT technique is used [4]. Depending on the maximum power point tracking algorithms used the variable duty cycle pulses can be generated for the converter.…”

This paper compares the performance of buck-boost and zeta converter fed solar photovoltaic module. The study is carried out by considering a solar pv module, dc-dc converter, MPPT controller and a resistive load. The voltage gain, output voltage ripple and output current ripple of the two converters were compared. Maximum Power Point tracking is implemented and and ensures the extraction of maximum power from the solar panel. Here MPPT is achieved by using perturbation and observation method. Zeta converter topology provides a non inverted output voltage with increased voltage gain. Output has lesser voltage and current ripple compared to buck-boost converter. Photovoltaic module with Buck-Boost and Zeta converter are simulated using MATAB Simulink software and the result are shown.

“…Normalmente, técnicas de MPPT tradicionais, as quais são baseadas em estratégias perturbativas, tais como condutância incremental (IC -Incremental Conductance) [8], [9] ou perturba e observa (P&O -Perturb & Observe) [8]- [12], têm sido usadas para realizar o rastreamento do ponto de máxima potência (MPP) do arranjo fotovoltaico. Embora os algoritmos de MPPT baseados nos métodos IC e P&O terem um bom desempenho considerando o arranjo fotovoltaico irradiado uniformemente, seu desempenho pode ser fortemente afetado quando estes estão operando sob condições de sombreamento parcial.…”

Resumo -Este artigo apresenta a implementação de um sistema fotovoltaico (PV) monofásico conectado à rede elétrica com duplo estágio de conversão de energia, o qual não é afetado por problemas associados a sombreamentos parciais. Técnicas convencionais de rastreamento de máxima potência, tais como perturba e observa, não rastreia o ponto de máxima potência global (GMPP) quando o arranjo PV opera sob condições de sombreamento parcial. Como resultado, o desempenho geral do sistema diminui. Este trabalho usa o método de otimização por enxame de partículas para rastrear o GMPP, aumentando o desempenho do sistema PV. Simultaneamente, o sistema fotovoltaico é controlado para realizar o condicionamento ativo de potência, realizando supressão das correntes harmônicas e compensação da potência reativa da carga. Além disso, como principal contribuição deste trabalho, é proposta uma malha de controle feed-forward para reduzir variações bruscas de tensão do barramento CC na ocorrência de transientes de radiação solar e/ou temperatura. Tais variações podem influenciar no desempenho do sistema PV bem como ocasionar danos às chaves de potência. Os desempenhos estático e dinâmico do sistema PV são avaliados por meio de resultados experimentais. Palavras-Chave PSO-BASED MPPT TECHNIQUE APPLIED TO A GRID-TIED PV SYSTEM WITH ACTIVE POWER LINE CONDITIONING USING A FEED-FORWARD DC-BUS CONTROL LOOP1 Abstract -This paper presents a double-stage conversion single-phase grid-tied photovoltaic (PV) system implementation, which is not affected to problems associated to mismatching phenomena, such as partial shading. Usually, conventional maximum power point tracking techniques, such as perturb & observe, do not track the global maximum power point (GMPP) when the PV array is operating under partial shading. As result, the overall PV system performance decreases. This paper uses Artigo submetido em 18/01/2016. Primeira revisão em 16/03/2016.

Simultaneously, the PV system is controlled to carry out the active conditioning, suppressing load harmonic currents and compensating reactive power. In addition, as main contribution of this paper, a feed-forward control loop is proposed to reduce sudden variations of the DCbus voltage, in occurrence of solar radiation and/or temperature transients. Such variations can influence the PV system performance and can also cause damage in the switching devices. The static and dynamic PV system performances are evaluated through experimental results.
