Projeto de um conversor CC/CC isolado do tipo push-pull em corrente para sistema de bombeamento fotovoltaico.

Abstract

With incisive concern with environmental issues and the need to bring the energy in isolated access to grid places, emerges as one of the applications of PV systems. The pumping system can be described as one of the aspects of this application, since its operation will need to give uninterrupted, because it is an isolated system and without batteries. The study was based on literature review of photovoltaic systems, in order to scale one of the modules that make up the system: The lift converter CC / CC. The topology used in the project was the push-pull converter fed current, which were scaled all drive components, in order to possess commercial values. They were also designed the measuring circuit voltage and input current and output voltage as well as protection circuits and energizing the keys so that the system works with maximum efficiency. The simulations were performed in Simulink / Matab where one can prove the projected results achieved the expected.
