Abstract. Renewable energy sources have attracted a lot of research interest in the past decade. Among these, solar energy is regarded as one of the promising energy sources and has been deployed worldwide with the installed capacity continually increasing. Solar-hydrogen systems have been under research for more than two decades. In such system, maximum power point tracking (MPPT) plays an important role to deliver maximum power from solar panels to the electrolyser. In this paper, two simple but effective MPPT methods are developed and evaluated. Differed from most of the existing methods, these methods are only reliant on a single current sensor input to locate the maximum power point of the solar panel.

“…Thus, under different loads, the duty cycle can be adjusted to change R in to match R opt at any cli- matic condition. Several methods are proposed for MPPT algorithm: system oscillation [1], look-up table [3], fractional open-circuit voltage [4], fractional short-circuit current [5,6], current sweep [7], perturbation and observe (P&O) [8], Hill Climbing [9][10][11], conductance incremental [12][13][14], a biological swarm chasing algorithm [15], Ripple correlation control [16], fuzzy logic control [17,18] and neural network [19]. However, the parameters' sizing of the different topologies of DC-DC converters has not been studied widely although this sizing affects significantly the optimum operation of the PV systems.…”

The DC-DC converters are widely used in photovoltaic generating systems as an interface between PV module and the load. These converters must be chosen to be able to match the maximum power point (MPP) of PV module when climatic conditions change with different resistive load values. So DC-DC converters must be used with MPPT controller in order to reduce losses in the global PV system. This article focuses on the effect of climatic conditions on design of two components (inductance, capacitance) for three topologies of DC-DC converters commonly used in PV systems. When climatic conditions change, the boundary of inductance and capacitance parameters of DC-DC converter will change. These two parameters must be properly sized to achieve optimal efficiency for each converter. The design optimization is based on two principles: 1) for a steady-state operation in a continuous conduction mode, the inductance value for all choppers must be greater than the maximum value of boundary inductance, and 2) in order to limit the output voltage ripple of DC-DC converter below a desired value, the filter capacitance must be larger than the maximum value of boundary capacitance.
