Simulation of various DC-DC converters for photovoltaic system

Abstract

This work explains the comparison of various dc-dc converters for photovoltaic systems. In recent day insufficient energy and continues increasing in fuel cost, exploration on renewable energy system becomes more essential. For high and medium power applications, high input source from renewable systems like photovoltaic and wind energy system turn into difficult one, which leads to increase of cost for installation process. So the generated voltage from PV system is boosted with help various boost converter depends on the applications. Here the various converters are like boost converter, buck converter, buck-boost converter, cuk converter, sepic converter and zeta converter are analysed for photovoltaic system, which are verified using matlab / simulink.

Fast photovoltaic IncCond-MPPT and backstepping control, using DC-DC boost converter

“…In this work, we choose to use DC-DC Boost converter to achieve load adaptation in order to make PV Module work at its maximum power point. We consider that this converter is more adequate for PV-MPPT control, because it allows us controlling input voltage , that is equal to PV Module voltage [26][27]. As showing Figure 7, the DC-DC Boost converter is composite of LC filter (L1, C1) for filtering input voltage ( ) and for decreasing current ripple of 1 , a switch (T), a diode (D), a capacitor (C2) and resistance load (R).…”

Modeling and simulation of solar PV module for comparison of two MPPT algorithms (P&O & INC) in MATLAB/Simulink

“…Two MPPT algorithm methods are proposed in this literature; Perturb and Observe (P&O) and Incremental Conductance (INC). For the representation of the MPPT, the PV system needs to have a DC‫ــ‬DC converter, the DC‫ــ‬DC converter can be either boost converter or buck‫ــ‬boost converter, they are usually used because of their efficiency high [7]. The boost converter is used in this paper to track the MPP.…”

Simulation, bifurcation, and stability analysis of a SEPIC converter controlled with ZAD

“…Dynamic systems defined in pieces are very important topics of study in theoretical and experimental matters, being investigated in depth in recent years. An example of systems defined in pieces, are DC-DC voltage converters, which allow the control of output voltage from a given voltage source; that is, they act as bridges for energy transfers between sources and loads, both of direct current [4]. This leads naturally to the question of how to transfer energy from the source to the load with amplitude, which needs a 1 voltage, with the minimum loss of power.…”
