Z-Source Converter with Ultra Gain for Transformer-Less Fuel Cell Integrated Single Phase Grid System

DC-DC Boost Converters with grid-connected systems make extensive use of high voltage gain components. that include renewable energy sources. The objective is decreasing prices and size by removing transformers and other power equipment with the goal of minimising conversion losses. This research suggests a high gain converter for HVDC and fuel-based applications. The boost-z source converter layout presented here minimises the number of input DC sources and switches. Switching stress and switching losses are reduced by using a high gain topology with a low duty cycle. Snubber protection is provided by the blocking diodes in the suggested converter architecture. The PI controller is employed in the converter for closed loop steady state voltage functioning. The Grid Synchronization approach is used to address power quality concerns. Matlab simulation was used to create this project.
