초록
This paper is to describe how to apply the Phase-shifted Full Bridge 100kHz high frequency soft-switching PWM method to 48[V], 200[A] DC/DC converter. The soft-switching is achieved from light load to full load by using phase-shifted zero voltage switching method with additional capacitors besides the MOSPET's of the right leg even though the leakage inductance of high frequency transformer is designed small. This method can reduce the switching tosses, EMI problems, and increase the effective duty. Also, this paper includes the simulation, analysis, and experiment results of the DC/DC converter unit.
