... is the common consideration in applications requiring a constant or nearly constant instantaneous output voltage í µí±£ í µí± í µí±¡ ≅ í µí± í µí± . Figure 14 shows the average inductor current in the buck-converter which is equal to the average output current í µí°¼ í µí± , the main reason behind this being the average capacitor current in the steady-state is zero. . In all our analysis, we assume that the converter operates in the continuous current conduction mode. ...

... response to the changes in the output load and the input line voltages there is always a specified tolerance band (e.g. ± 1% around its nominal value) within which the output voltages of the DC power supplies are regulated. A negative-feedback control system is used to accomplish this as shown in figure 15. Here the output voltage í µí±£ í µí± of the converter is compared with a reference value í µí± í µí±,í µí±í µí±í µí± . ...

More sophisticated applications require electronic converters to process the electricity from the PV device. These converters may be used to regulate the voltage and current at the load, control the power flow in grid-connected systems, and mainly track the maximum power point (MPP) of the device. Therefore, this paper tries to study an electronic converter in PV systems, namely the Buck converter, and propose an easy way to electronic converter designers to calculate component values needed to realize it.
