“…It is clear that real power converges, during the steady-state, to a value (E) slightly lower than the array's maximum power (B). The difference between the generated real power and the optimal panel power contributes to the performance assessment of the proposed analog technique [25][26].…”

The tracking of the maximum power point (MPP) of a photovoltaic (PV) solar panel is an important part of a PV generation chain. In order to track maximum power from the solar arrays, it is necessary to control the output impedance of the PV panel, so that the circuit can be operated at its Maximum Power Point (MPP), despite the unavoidable changes in the climate conditions such as temperature and Irradiance. A new MPPT analog technique to track the Maximum Power Point (MPP) of PV arrays is proposed. This new technique uses simple and classical functions of electronic circuits. An Off-Grid PV system was considered to apply and validate the proposed new technique. The entire circuit was implemented in circuit-oriented simulator Proteus-ISIS. We present the results associated with the design, the realization, and the experimentation of a PV system equipped with a new analog MPPT command. The obtained results have shown good efficiency of analog technique (more than 98.5%). The second part of the paper consists of the description of the design and the realization of the novel analog MPPT integrated chip. The integrated circuit (IC) was designed and realized using HV CMOS technology 0.35-µm.

“…But in proposed system the efficiency is 98% because of using voltage multiplier and coupled inductor. Here MPPT algorithm (P & O algorithm) is used to track maximum power from solar panel at different irradiation [7][8]. An isolated coupled inductor coordinated DC-DC converter with a snubber circuit to lessen the voltage spike on switches.…”

This paper concentrates on the design of DC multiplier for solar photovoltaic application. The main aim of this paper is to boost up the voltage from solar panel without using transformer and to track maximum power using maximum power point algorithm. The system design includes solar panel, snubber circuit, switching circuit, coupled inductor, opto isolator, voltage multiplier, microcontroller and load. Normally boost converter is used in conjunction with solar PV to boost the output voltage from panel. But the boost converter can be able to increase the input voltage to a limited value. In other, converter transformers are used. Hence core loss, magnetic loss and copper loss will occur. To overcome these losses and also to achieve isolation coupled inductor can be used. Thus proposed system overcomes the core loss, magnetic loss, copper loss and also helps to achieve the isolation between the circuits by using the coupled inductor. By using voltage multiplier, the boost converter can able to increase the input voltage beyond the rated value. Simulations are done in MATLAB/Simulink platform. It forms the voltage multiplier for renewable energy application to boost the DC voltage.

“…Alternatively, the MPPT can be implemented by analog circuits [13][14][15]. The potential benefit from analog solution is that the MPPT can be integrated with DC-DC controller such that "plug and play" can be expected for many low power PV applications.…”

A new analog technique is proposed in order to track the maximum power point (MPP) of PV panels. The proposed technique uses the well-known simple functions of electronic circuits. The proposed technique is validated by applying it to boost based off grid PV system. The simulation of the PV system was done on the circuit oriented simulator Proteus-ISIS. A good efficiency of the analog technique (more than 98%) was registered. The variation of irradiation was introduced in order to study the robustness of the proposed analog MPPT technique.
