Performance assessment, in terms of ripples and power, of conventional and interleaved converter DC–DC with coupled and independent inductors dedicated to photovoltaic installations

Abstract

<table class="Grilledutableau1" width="593" border="1" cellspacing="0" cellpadding="0"><tbody><tr><td valign="top" width="387"><p>Our work focuses on the design and analysis of an interleaved Boost converter DC-DC with coupled and independent inductors in terms of ripples and power. An interleaving strategy is adopted to minimize the currents in the Boost components and consequently to miniaturize them. The command shift of the switch by the X.T value (X: shift coefficient 0<X<1 and T: period of the command signal), minimizes the ripple of the input current and output voltage and maximizes the power extracted from the photovoltaic system. The coupling technique of inductances of interleaved Boost, furthermore reduces the ripples of the input currents and further maximizes the power extracted from the photovoltaic panels. To determine the variation of the power extracted from the PV, according to the duty cycle D and the switches command shift X.T, the duty cycle, was manually varied (Similar to a MPPT command). For this we modeled, under MATLAB/Simulink, the photovoltaic system, the power interface (DC/DC Boost interleaved). Finally, a prototype of interleaved Boost converter with coupled inductors and a shifted control of the switches was realized. Experimental results have been proposed to validate the results of simulations.</p></td></tr></tbody></table>

Small-signal modeling of current-mode controlled modular DC-DC converters using the state-space algebraic approach

“…The four basic arrangements are: the parallel-input/parallel-output (PIPO), the parallel-input/series-output (PISO), the series-input/parallel-output (SIPO), and the series-input/series-output (SISO). Various dc-dc converter topologies like the buck and buck-based [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], the boost and boost-based [11,[19][20][21][22][23][24][25][26][27][28][29], and the buck-boost-based [25,[30][31][32] have been used for the constituent modules of modular converters. The semiconductor devices employed in these converters are commonly driven using pulse-width modulation (PWM) techniques with the converter being operated under voltage-mode control (VMC) or current-mode control (CMC) [1, 2, 4, 6-10, 12, 13, 16, 17, 19-26, 31, 32].…”

A novel approach for the fastest MPPT tracking algorithm for a PV array fed BLDC motor driven air conditioning system

“…Unavailability of conventional fuel resources and specific concern about increasing pollution has certainly led the world towards pollution free alternative sources. If one considers the existing problems solar power generation appears as the sole answer to every problem [1][2][3][4][5][6]. This is the natural energy source which is a lot helpful and free from producing pollutants in great number, secondly it is freely available in the nature and moreover carbon emission can be marginalized to a greater.…”

Design and modeling of optical reflectors for a PV panel adapted by MPPT control

“…Renewable energy sources such as photovoltaic cells, fuel cells, wind energy. etc., is one of the most reliable remedies for saving electrical energy [1,2]. These sources require an energy conditioning system.…”

“…These sources require an energy conditioning system. Indeed, the voltages and currents produced by photovoltaic panels need to be improved in terms of ripples quality and efficiency [1]. Boost converters are often used to form a more robust power distribution system and more stable currents.…”

“…Boost converters are often used to form a more robust power distribution system and more stable currents. This distribution mode is commonly used for applications requiring currents exceeding tens of amperes [1,3].…”
