Full textThe duala, a small bantu-speaking population group located in coastal cameroon, emerged during the pre-colonial and the colonial periods as a powerful economic force. They lacked the usual forms of wealth, basing their strategy of production in a two-fold system of social networks : one made up of their allies and the other of their dependents. In 1884, germany established a protectorate over cameroon and this eventually resulted in duala middlemen traders being evicted from their role as exclusive brokers in local trade. Cocoa growing then provided an opportunity for the most successful duala merchants to reinvest the material assets previously used in commercial activities in new and lucrative ventures. Thus using land and slaves from trade, the duala opened up in the 1890s large cocoa plantations in the inland regions. In 1907, they expanded their cocoa farms in the tiko lowlands. The expension of duala cocoa enterprises brought about changes in the earlier pattern of land acquisition and the labour relationship between duala planters and their servile workers. Throughout the french mandate period, duala entrepreneurs invested in real estate, academic education, and timber businesses and somehow succeeded in adapting their entrepreneurial skills and strategy to a changing environment by a cunning manipulation of social relations

Full textThis thesis proposes to improve the efficiency of public illumination systems by means of AC chopper based power converters. A comparative study of high performance AC/AC converters feeding high pressure sodium lamps on mains frequency is presented. These converters are obtained using standard DC/DC topologies with bi-directional switches (four quadrants). A high pressure lamp ballast design methodology is also presented, based on the suppositions of high input power factor and without exciting acoustic resonances at destructive levels. The topologies used are the Buck-Boost, Ćuk, SEPIC and ZETA operating on continuous current mode, with or without input filter, and an ignition circuit. The converters' switching frequencies are 33 kHz feeding the lamp at low frequency (mains frequency). The ignition circuit providing the high voltage required to guarantee the initial arc to start-up the lamp, is presented, analyzed and optimized in the thesis. To control the ballast a 32 bits microcontroller is used, contributing to reduce the component count and the overall system cost. The base to propose a new control design methodology and power circuit parts specification is the Brazilian standards and a comparison with the electromagnetic ballasts output waveforms. Experimental results supplying a 70 W HPS lamp, connected to the mains (220 V ±20% e 60 Hz) through the proposed ballasts, are presented in order to validate the thesis.
Este trabalho visa aprimorar os sistemas de iluminação pública aplicando reatores eletrônicos baseados em conversores CA/CA. Apresenta-se um comparativo entre conversores tradicionais CC/CC, aplicando a eles interruptores bidirecionais em tensão e corrente, de modo a alimentar a lâmpada de alta pressão de sódio na frequência da rede de alimentação, formando um conversor estático CA/CA com alto rendimento. Apresenta uma metodologia de projeto para fonte de alimentação de lâmpadas de descarga em alta pressão baseada em reatores eletrônicos com alto rendimento e elevado fator de potência, que não excitam de forma destrutiva a ressonância acústica (AR). O reator consiste dos conversores Buck-Boost, Ćuk, SEPIC e ZETA bipolares operando por modulação de largura de pulso (PWM) em modo de condução de corrente contínua (CCM), com ou sem filtro de entrada acoplado e com um circuito de ignição. O conversor opera em 33 kHz e alimenta a lâmpada na frequência da rede. O circuito de ignição fornece a alta tensão para a formação inicial do arco elétrico e neste trabalho de doutoramento foi equacionado e otimizado quando comparado ao modelo tradicional. O controle do reator é implementado em um microcontrolador de 32 bits, o que contribui com a redução do número de componentes e do custo final do sistema, sem prejudicar a confiabilidade do mesmo. As formas de onda de saída de reatores eletromagnéticos e as normas vigentes servem de base para o dimensionamento dos componentes e a obtenção de uma nova metodologia de controle. Resultados experimentais para uma lâmpada HPS de 70 W alimentada a partir de uma rede de 220 V ±20% e 60 Hz são apresentados para validar os reatores propostos.

Este trabalho apresenta o estudo de um conversor CA-CA com tensão eficaz de saída controlada e freqüência constante, destinado à aplicação em eletrodomésticos alimentados em tensões "bi-volt", e que utilizam acionamentos com motor de indução monofásico. Na escolha da topologia, foram levados em conta fatores como a faixa de operação do conversor (tensões de entrada e saída), potência do equipamento, o rendimento, o atendimento às normas de segurança, compatibilidade eletromagnética, qualidade de energia e, principalmente, o custo. Duas topologias de conversores CA-CA indiretos com capacitor de barramento da ordem dos F são escolhidas para um estudo das características peculiares e suas implicações. São analisadas formas adequadas de controlar as estruturas e uma delas é escolhida para implementação de um protótipo a fim de se comprovar os resultados teóricos. Um protótipo com potência de 500W e tensão de saída de 110V para uma carga R-L com fator de deslocamento superior a 0,6 é implementado, sendo alimentado em 110V e 220V. Toda a metodologia para o projeto é apresentada sequencialmente, desde o estágio de potência até os estágios de comando e controle, sendo os resultados experimentais comparados com os resultados teóricos, validando o estudo.
