چکیده: Abstract: Direct current power supplies are widely used in many modern equipment. The problem of many designers is to design a power supply capable of working in a wide range of input voltage changes. Also, the demand for using multi-output power supplies with low voltage and high current has increased. A multi-output converter must meet conditions such as: high efficiency in different load conditions, voltage regulation, isolation and compact size, it must have a favorable condition in terms of magnetic interference. Flyback topology is the most attractive choice due to its relative simplicity in comparison with other topologies used in low-power applications, and we can easily achieve multiple outputs. To achieve this, printed circuit simulation is one of the fast and low-cost tools used in the field of electronics. In this thesis, the goal is to develop this method in switching converters and especially multi-output flyback. Among the goals of this research are: 1- Simulating the physical layer of the printed circuit- 2- Presenting a summary of the simulation results- 3- Presenting topological changes to improve the performance of the converter circuit. To carry out this research, a proven design of a flyback converter should be based on the work, then the theoretical accuracy of the design should be confirmed by simulating the designed schematic. The approved circuit is simulated by the software with the parts modeled by the developers to achieve a more realistic response. The printed circuit is designed with conventional requirements and the physical layer is simulated in the software environment. The obtained results are examined in terms of electrical and magnetic aspects and the results are recorded. According to the obtained summary, topology corrections are made and the validity of the hypothesis presented in the previous part is confirmed
