“…The first continuously track voltage and current, in order to dynamically adjust the power operation point, without the need for any empirical information. Algorithms like perturb and observe (P&O), incremental conductance (IC), or hill climbing (HC) belongs to this category [47][48][49] and are characterized by high hardware, complexity, continuous functionality, and high efficiency, especially if the behavior of the energy source is unknown. Other MPPT techniques like fractional open-circuit voltage (FOCV) or fractional short-circuit current (FSCC) requires less complexity and measured data, without the need of continuously track the input voltage and/or current since they rely on a priori information about the source [50,51].…”

In this work, an identification technique of a simple, measurements-based SPICE (Simulation Program with Integrated Circuit Emphasis) model is presented for small low-cost Peltier cells used in thermoelectric generator (TEG) mode for low-temperature differences. The collection of electric energy from thermal sources is an alternative solution of great interests to the problem of energy supply for low-power portable devices. However, materials with thermoelectric characteristics specifically designed for this purpose are generally expensive and therefore often not usable for low cost and low power applications. For these reasons, in this paper, we studied the possibility of exploiting small Peltier cells in TEG mode and a method to maximize the efficiency of these objects in energy conversion and storage since they are economical, easy to use, and available with different characteristics on the market. The identification of an accurate model is a key aspect for the design of the DC/DC converter, in order to guarantee maximum efficiency. For this purpose, the SPICE model has been validated and used in a design example of a DC/DC converter with maximum power point tracking (MPPT) algorithm with fractional open-circuit voltage. The results showed that it is possible to obtain a maximum power of 309 µW with a Peltier cell 2 × 2 cm at a ΔT of 16 °C and the designed SPICE DC/DC converter performance proved the improvement and optimization value given by the TEG model identification.

“…This algorithm has been adopted by researchers to investigate the PV system's performance [37]- [40]. Also, it is chosen due to having some advantages, consisting of less computational procedure, ease of implementation, low complexity, and low power consumption [41]- [44]. Moreover, P&O is one of the most industry prevalent algorithms besides incremental conductance (INC) and constant voltage (CV) [45].…”

<span lang="EN-US">Single-ended primary-inductor converter (SEPIC) was considered a good alternative to a DC-DC converter for photovoltaic (PV) systems. The SEPIC converter can operate with an input voltage greater or less than the regulated output voltage, or as a step-up or step-down. As a step-up converter, SEPIC boosts PV voltage to specific levels. However, gain limitation and voltage stress continue to reduce the efficiency of conventional SEPIC converters. Because of this, researchers created a modified SEPIC converter to improve performance. In this paper, six modified SEPIC converters were compared and evaluated. To compare fairly, all modified SEPIC converters are non-isolated and use a single switch. Power simulator (PSIM) software was used to simulate each converter with a BISOL BMO-250 PV module and maximum power point tracking (MPPT) P&O controller. The converter with the highest static voltage gain and lowest duty cycle has been identified. It results in up to ten times voltage increment with a 0.8-duty ratio. All topologies have the same voltage stress, with maximum and minimum values of 30.1 and 29.5 V, respectively. On the other hand, each topology produces different average efficiencies, with the highest and lowest efficiency at 99.5% and 97.2%, respectively.</span>

“…It is based on how current and duty cycle relate to one another. [10] The comparison analysis between modified MPPT algorithm and conventional P&O algorithm was done by [11,12] MPP algorithm and PI controller is used in this work and it had been observed that the steady-state and dynamic performance was quite satisfactory. Also the proposed system gave satisfactory results when operated under 30% of insolation levels.…”

The renewable energy source that is now expanding the fastest is solar energy. It is expanding quickly because of its many applications and affordable upkeep. In order to maintain a consistent output voltage, the DC-DC power electronic converter is integrated with the solar PV system. This study examines SEPIC and ZETA converters in conjunction with a solar PV array. In this study, many characteristics like DC voltage, inductance, capacitance, and voltage are discussed. This research also compares and contrasts the SEPIC and ZETA converters. The MATLAB/Simulink environment is used for all work. When all the parameters are set to certain standard values, waveforms are produced. This demonstrates how changing a few parameters could produce distinct waveforms.
