Crystallographic Orientations

We have measured the differential current-voltage characteristics of normal metal-NbSe3 direct point contacts (without insulating barrier) formed along different crystallographic orientations under applied magnetic field with different orientations. At low temperature two energy gaps, $\Delta_{p1}$ and $\Delta_{p2}$, corresponding to the high and the low-temperature CDW were observed simultaneously as a singulanty of the excess resistance which is attributed to an analog of Andreev reflection, in which the incident electron reflects on the Peierls energy gap barriers with its charge unchanged. An applied magnetic field up to 8.5 T does not lead to a change in the density of states and in the Peierls energy gaps, suggesting that the large magnetoresistance observed in NbSe3 might not result from the change in the CDW order parameter with magnetic field but rather from the increase of scattering of non-condensed to CDW carriers.

In order to understand the importance of MPPT algorithms, modeling and simulation of a PV system with and without MPPT algorithm using MATLAB/SIMULINK under different irradiance and temperature variations are analyzed in this chapter. The MPPT technique used is Incremental Conductance (INC) algorithm. First of all, the P-V (power-voltage) and I-V (Current-Voltage) characteristics are noticed for different values of solar irradiance while keeping the cell temperature constant. Later on, for different temperature values with constant irradiance levels the characteristics of PV panel has been studied. The effect of temperature and irradiance on power, current, voltage and duty ratio of the PV system with and without INC MPPT algorithm is analyzed for understanding the importance of MPPT techniques in PV systems
