Abstract
DC-DC converters are widely used in applications such as power supplies for electronic devices, Renewable energy system, electric Vehicles etc. DC-DC converters are classified into different types based on the topologies used for voltage conversion. In this article a non-isolated DC to DC boost converter having high voltage gain for voltage sources with low input is created which enable the use of PI Controller for improved performance of the whole system. Here a two-inductor boost converter was combined with a voltage multiplier, switched capacitor cells to make a high-voltage-gain dc-dc converter. The Proposed converter have high voltage gain, simplicity of operation, lower voltage, and lower current stresses on the components. . There are constant voltage variations for converters' outputs as a consequence of changes at the load and source end. In order to achieve a constant output voltage regardless of the source or load change, proportional integral controller is also employed in the proposed system.
