Its mode of operation differs from that of the linear regulator power supply. The objective of this dissertation is the study and simulation of a flyback type galvanically isolated switching power supply which is widely used in the domestic and industrial fields. The main advantages are good efficiency, low cost, relatively small size and light weight. The performance of this type of power supply is verified by simulation using Matlab / simulink software.Flyback converter, power supply, PID controller.
