Problem Statement In electrical engineering the low cost, simplicity of design and intrinsic efficiency of flyback transformers have made them a popular solution for power supply designs of below 100W to 150W. Other advantages of the flyback transformer over circuits with similar topology include isolation between primary and secondary and the ability to provide multiple outputs and a choice of positive or negative voltage for the output. The flyback regulator can operate in either discontinuous or continuous mode. In the discontinuous mode the energy stored in the core when the FET is on/off is completely emptied from the core during the flyback period. In the continuous mode, the FET is turned on before the core empties of flyback energy. A typical flyback transformer may operate in both modes depending on the load and input voltage. Designers should consider the maximum load at low voltage, including all conditions within the operating range of the flyback, as it will simply shut down (discontinuous mode) between cycles and wait for the load demand to catch up with the power-delivery capability. This is one of the most dynamic characteristics of the flyback, regulated over a wide range of input voltage and load. Deliverables The project is due on 15 june, 2020. Your proposal must have 1) Circuit diagram flyback transformer. 2) Dimensions of all parameters. 3) Cost of equipment. 4) Chart of comparison with other converters.
