Abstract :
This paper deals with the dc magnetic biasing of high frequency transformer of the isolated full bridge converter. Analytical calculations are given detailed based on the modes of the converter considering leakage inductance. Herewith, the impact of the source, load, leakage inductance, magnetizing inductance and line resistance on dc magnetic biasing is considered and analyzed. Finally simulation results are presented to verify the validity of the analytical calculations.
