Abstract:
Renewable energy is considered to be one of the most promising alternatives for the growing energy demand in response to depletion of fossil fuels and undesired global warming issue. With such perspective, Solar Cells and Fuel Cells are most viable, environmentally sound, and sustainable energy sources for power generation. Solar and Fuel cells have created great interests in modern applications including distributed energy generation to provide clean energy. The purpose of this thesis was to perform a detailed analysis and modeling of Solar and Fuel cells using Cadence SPICE, and to investiga

A rake receiver, which resolves multipath signals corrupted by a fading channel, is the most complex and power consuming block of a modem chip. Therefore, it is essential to design a rake receiver be efficient in hardware and power. We investigated a design of a rake receiver for the WCDMA (Wideband Code Division Multiple Access) system, which is a third generation wireless communication system. Our rake receiver design is targeted for mobile units, in which low-power consumption is highly important. We made judicious judgments throughout our design process to reduce the overall circuit co

Abstract:
The competitive market of wireless communication devices demands low power and low cost RF solutions. A quadrature local oscillator (LO) is an essential building block for most transceivers. As the CMOS technology scales deeper into the nanometer regime, design of a low-power low-voltage quadrature LO still poses a challenge for RF designers. This dissertation investigates a new quadrature LO topology featuring a transformer-based voltage controlled oscillator (VCO) stacked with a divide-by-two for low-power low-voltage wireless applications.

La récupération d'énergie vise à réaliser des dispositifs électromécaniques de taille centimétrique permettant d'alimenter des systèmes électroniques en puisant de manière opportuniste l'énergie du milieu environnant. Parmi les différentes sources disponibles (solaire,thermique etc.) les vibrations ambiantes sont susceptibles de fournir assez de puissance pour alimenter des microsystèmes autonomes tels que des noeuds de réseaux de capteurs communicants. L'enjeu consiste à concevoir des microgénérateurs effectuant la conversion de cette énergie mécanique ambiante en énergie électrique exploitab

It is necessary to judge the influences of producers on the electric compounds while creating electrical energy or during the regulation of those existing. These analyses are sorted out by so called studies of connectivity. These calculations analyze the degree of connection of the producer and the standby unit during a break-down. The results of this report are several recommendations for creating such unit and succeeding steps leading to secure the stability and safety of the electric compound operation.

This paper use of DC / DC converter through the rectifier with the difference of the wind turbine generator output to produce a different DC voltage into a sufficient battery charge voltage.

Abstract:
Multilevel inverters have advantages over two-level inverters such as reduced THD, ability to operate at low switching frequencies, reduced switching losses etc. Moreover, higher voltage levels can be handled with devices of lower voltage rating. The main disadvantage with the multilevel configurations compared to the two-level inverter configuration is the increase in the number of power devices required and the circuit complexity, which necessitates complex control schemes that add to the cost. Also, the reliability of the converters comes down as the number of devices increases. Reduction i

Abstract:
Broadband, millimeter-wave signals can be generated by using frequency multipliers that are cascaded by broadband power amplifier at the output. This approach has the potential to generate an electronically tunable signal with adequate output power over a wide range of frequencies. In this work, important issues including device modeling, broadband amplifier design and frequency tripler design are investigated. New equations for modeling the drain current, the gate-source and the gate-drain capacitances for HEMT have been proposed. The parameters of the proposed drain current model can be extr

Each element in the electrical circuit is introduced and the behavior of this circuit is simulated using commercial code MULTISIM.The DC voltage output is investigated through harmonic vibration input and their relations are compared. Furthermore, the output voltage is simulated at different output loadings when the input voltage is an impulse function. Results show that the output voltage decays very fast as the output loading is very large.
