Abstract
Power electronic converters have undergone major advancements in last few decades and have influenced human life in many aspects. Design of any converter is an arduous task. One of the major challenges faced in converter design is to drive high-side MOSFETs, since the source terminal has no specific reference. To address this, isolated supply employing flyback topology is designed to provide proper reference to top switches. In the current design, twelve isolated power supplies are generated to cater a requirement of four-leg system. The flyback topology is operated in discontinuous conduction mode and accepts universal voltage inputs. The current-mode PWM controller is used to generate necessary gate signal for the flyback MOSFET. Theoretical approach towards the flyback converter design, transformer windings and snubber calculation are discussed in this paper. Simulations are carried out using MATLAB/Simulink and compared with the practical results.
