ABSTRACT
The single-ended, forward converter gets its name from a family of converters. One of the main reasons for engineers to use the single-ended, forward converter circuit is the problem they have with the push-pull converter, core saturating. The core saturation can be due to an imbalance of the primary or secondary. The average input current for the single-ended, forward converter is about the same as the push-pull converter, but the peak current is always greater than twice the average current. The input filter and output filter for the single-ended, forward converter are always larger than the push-pull converter, because it is operating at the fundamental frequency. The output filter inductor for Switch-Mode Power Supplies, probably has been designed more times than any other single component. However, the core loss in the output inductor of a switching regulator is much lower compared to the core loss in the main converter transformer.
