Abstract
This paper presented the power losses comparison results with the Active clamp Forward, the Asymmetrical half bridge and the Two transistor forward converters. To estimate for conduction losses in the converters, the steady state analysis regard to parasitic resistance and current effective values for main parts of converters was derived. In addition, the theoretical efficiency for the converters with input voltage 400V, output voltage 12V and maximum power 480W was discussed.
