Abstract:

Providing the required load power using Switch Mode Power Supplies (SMPS), leads to smaller and more efficient converters. Flyback converter is one of the most famous topologies in use. Flyback converter is equivalent to buck-boost converter with the inductor split to form a transformer.

The operating principle of two converter is very similar. Both transfer energy to the load when switch is in off state. Also, both suffer from Right Half Plane (RHP) zero when operating in Continuous Conduction Mode (CCM). Flyback transformer is the most important part of flyback converter.

This paper develops a software package to model the flyback transformer based on simple measurements. Developed software solves a set of nonlinear equations to obtain the model parameters. Designing of snubber circuit can be done based on the obtained model. Developed software is free of charge. Contact authors to receive the software.
