ISRAEL FRANKLIN DOURADO CARRAH FORTALEZA DEZEMBRO DE 2010
Trabalho Final de Curso submetido à Universidade Federal do Ceará como parte dos requisitos para graduação em Engenharia Elétrica. Orientador: Prof. Dr. René Pastor Torrico Bascopé. Co-orientador: Eng. Luiz Daniel Santos Bezerra.
With the advance of technology and the emerging digital processors more powerful and cheaper, discrete control techniques are being increasingly applied in Power electronics converter. In most cases, the significant reduction of weight and volume and the price reduction are the main reasons by opting for digital control. This project consist of the voltage inverter full bridge type with an LC filter using unipolar modulation to obtain sinusoidal voltage similar to the power grid. The converter control is accomplished through a currente loop and an other of voltage across the dsPIC30F2020 (digital modulator and digital controller), using the principles of the discrete control. This system is capable of converting 200Vdc into 110Vac and 60Hzwith efficiency equal or greater than 90%. The inverter has its theorethical study developed and design of all the components presented. In the end, are shown the simulation results of various situations which the inverter can be submitte
