“…A PWM-based charge controller can be used to maximize output power depending on the temperature of both the panel and the irradiance condition [20]. The SEPIC converter could also be controlled by a PWM-based charge controller to ensure a stable load voltage [21]. Nevertheless, some key considerations such as self-consumption, electromagnetic interference (EMI), the algorithm of fixed frequency current mode control, surge voltage, and lightning protection were not identified.…”

Reducing the self-power consumption of an off-grid solar home system is an economic model in which consumer employs photovoltaic (PV) system for its own electrical requirements. The latch-based clock gating approach has been employed in existing solar charge controllers to reduce integrated circuit (IC) power being used in the low-powered intended mode, although the reducing power is limited. This paper presents a self-power reduction technique based on wake-up power and latch-hold time; which minimize power supply during idle time for a solar home system. Wake-up power introduces a push-switch mechanism using typical transistor technology. Latch-hold time function is designed using an operational amplifier and negative-positive-negative (NPN) transistor. A technique with dynamic self-supply mechanism is also introduced for decreasing self-power consumption. The self-power consumption is identified via simulation studies where the result shows that the power usage is 70% lower than traditional approaches. This is determined using a simulated wave-shape analysis.

“…Another structure with a reduced input current ripple and higher step-up capabilities is presented in [44]. In [45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60], different structures of nonisolated SEPIC converters with some examples of design, analysis and control are presented. In [61], the classical SEPIC with isolation is presented, analyzed, and implemented.…”

In this paper, a new hybrid SEPIC dc-dc converter with coupled inductors suitable for photovoltaic applications is presented. First, how the new topology was derived will be presented, continuing with its analysis and design equation as a standalone dc-dc topology. The analysis will consist of a steady-state equations derivation, a static conversion ratio calculation based on which the semiconductor voltage and current stresses are evaluated and states the continuous conduction mode (CCM) operation conditions. The converter will then be simulated as a first validation of the theory using the dedicated Caspoc power electronics package. To finally validate the theoretical design, a prototype will be built in order to practically demonstrate the feasibility of the proposed solution and to reveal its main practical features and limitations. A comparative study to several other similar topologies will be carried out to identify its most desirable feature. Finally, an application of the new hybrid converter will consist of a complete solar energy conversion system using a photovoltaic panel. The maximum power point tracking (MPPT) algorithm will be elaborated. The solar system together with the MPPT will first be modeled, then simulated and practically implemented and tested.

“…Dc-dc converters are used in a large variety of applications: unidirectional and bidirectional chargers in automotive, renewable energies in photovoltaic cells for example, dc grids, cellphones, computers, laptops and so forth. These power circuits should be able to step-up [1][2][3][4][5][6][7][8][9], step-down [10][11][12][13] or step-up/step-down [14][15][16][17][18][19][20][21] the voltage from the input. The polarity of the output voltage can be the same [1][2][3][4][6][7][8] or reverse [5,[22][23][24][25][26][27][28][29] compared to that of the input voltage.…”

“…Therefore, depending on the application requirements, considering the few parameters mentioned before, different types of converters exist on the market. Because this paper introduces a newĆuk topology, different types of both step-down/step-up converters have been analyzed [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. If isolation is not necessary, the classical Buck-Boost converter [30] can be used.…”

This paper proposes a new hybrid Ćuk-type converter employing two inductors built on the same core which can be successfully used in applications requiring an output voltage considering higher than the input one. With few components added, in the proposed converter the static conversion ratio can be easily extended becoming wider compared to the classical Ćuk topology. At the same duty cycle range the output voltage is higher than in the classical Ćuk converter. The output voltage remains with negative polarity and with a reduced ripple. An advantage of the new converter is given by its two degrees of freedom. A DC and AC analysis is carried out, device stresses are evaluated and a comparative analysis of the proposed hybrid Ćuk topology to other indirect converters has also been performed. All the equations necessary for designing the converter are provided. The simulations performed together with the practical experiments carried out, all results confirm that the theoretical considerations are correct and validate the features that the proposed converter can provide a higher static conversion ratio without operating at high duty cycles.
