Özet

Environmental friendly energy sources like solar, fuel or wind cells provide low voltage levels. Grids work with higher voltage levels so step up is required before connecting these new energy sources to grid. Conventional boost converter is not able to provide a large DC gain. There are some topologies available in literature which provides required high DC gain. Without a suitable control system, converter's output may change due to disturbances like: Input voltage's changes and output load's changes. This paper designs a controller for one of the recently proposed high DC gain topologies. Converters dynamical equations are extracted using State Space Averaging (SSA). Controller is designed based on the obtained dynamics. Close loop system has been tested in Simulink (R) environment. Simulation results showed the performance of designed controller.
