It has variety of application. It behaves differently in different conduction mode. In this thesis a buck converter is designed first considering the design parameters. Then the designed circuit is driven to boundary, continuous and discontinuous mode to analyze the circuit. The gain and efficiency of the circuit has also been found out. A clear picture is drawn for the theoretical and simulated circuit. For continuous mode the circuit simulation shows exact behavior but in discontinuous mode there is some discrepancies. All of these issues are covered in the thesis.45 pagesenBRAC University theses are protected by copyright.
