This paper has shown the power density of a Faraday-type Magnetohydrodynamic (MHD) generator considering the presence of electrode voltage drop. The electrode of the MHD generator used in this paper is a segmented type, therefore there is a reduction of electrical conductivity and Hall parameter. The paper has also defined a load factor to express the effects of voltage drop on the electrode to the output power of an MHD generator. The results obtained from this paper have been analyzed and compared to the previous results where the voltage drop of the electrode is not considered. As a result, the segmented electrode and the voltage drop have affected significantly to the characteristics of the output power. This result is significant for optimization of the MHD generator with respect to the maximum power density.

Abstract Hot-carrier luminescence emission is used to diagnose the cause of excess quiescence current, IDDQ, in a low power circuit implemented in CMOS 7SF technology. We found by optical inspection of the chip that the high IDDQ is related to the low threshold, Vt, device process and in particular to transistors with minimum channel length (0.18 μm). In this paper we will also show that it is possible to gain knowledge regarding the operating conditions of the IC from the analysis of optical emission due to leakage current, aside from simply locating defects and failures. In particular, we will show how it is possible to calculate the voltage drop across the circuit power grid from time-integrated acquisitions of leakage luminescence.

Background: The improvement of the voltage in power lines and the respect of the low voltage distribution transformer substations constraints (Transformer utilization rate and Voltage drop) are possible by several means: reinforcement of conductor sections, installation of new MV / LV substations (Medium Voltage (MV), Low Voltage (LV)), etc. Methods: Connection of mini-photovoltaic systems (PV) to the network, or to consumers in underserved areas, is a well-adopted solution to solve the problem of voltage drop and lighten the substation transformer, and at the same time provide clean electrical energy. PV systems can therefore contribute to this solution since they produce energy at the deficit site. Results: This paper presents the improvement of transformer substation constraints, supplying an end of low voltage electrical line, by inserting photovoltaic systems at underserved subscribers. Conclusion: This study is applied to a typical load pattern, specified to the consumers region.
