    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (967 KB) | HTML iconHTML

    This paper presents an experimental study on the effect of the voltage on the electrolytic capacitors mounted in reverse polarity. The experiments indicate that if the capacitors are charged with a constant current, the voltage across them tends to slowly oscillate due to the fact that the leakage current becomes very high instead of being closely to 0. The study is performed on 3 types of electro... View full abstract»

    Targeting of the phenomena which arises when the electric current is passing through the human body leads to the definition of some equivalent electric circuits. The parameters of the passing segment of the current through the skin were studied. For this, an original measuring device was conceived and built using a digital control unit based on a PIC16F870 microcontroller. View full abstract»

    This paper presents an experimental method for determining the thermal conductance variation with temperature of a thermoelectric module (TEM). In general when building a Spice model for the TEM, the temperature variation of the internal parameters is not taken into account. This leads to errors when high accuracy is desired in designing and simulating TEM based applications. The authors propose a... View full abstract»
