“…In the proposed analog MPPT technique, we obtained a good efficiency of the technique compared to the analog techniques proposed in literature [22,23] (varying between 95% and 99.5%). If we compare our technique to the best one, allowing a comparable efficiency, published in literature, we can find that the proposed technique uses a low number of discrete devices and only one multiplier circuit is used.…”

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.

“…Photovoltaic cell provides a maximum power point (MPP) that varies according to the sun's irradiance variation and temperature . This is achieved through analogue or digital Maximum Power Point Tracking (MPPT) controls (Salameh et al, 1991;El Ouariachi et al, 2009). A significant number of MPPT control systems have been developed, starting with simple techniques, such as voltage or current variations .…”

In the case of the analogue MPPT control, there is a problem of congestion divergence of the electronic components used (Shraif, 2002;El Ouariachi et al, 2009).

This work aims to study and design a nonlinear gain scheduling control technique for a solar photovoltaic (PV) water pumping system. The efficiency and performance of the system will be fully investigated via a simulation study; which will be designed with regards to real constraints in a remote area of the Hail region in the Kingdom of Saudi Arabia. This work investigates a sunlight tracking system used to direct a photovoltaic module. The thoroughly examined system consists of a PV generator, a buck converter and a DC motor pump. For this purpose, we will develop a control strategy that enables us to find and track the "Maximum Power Point Tracking," so that maximum power is continuously generated.

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.
