Abstract

The proposed control for DC/DC converters with high frequency isolation, on one hand, provides fast stabilization to the DC microgrids without introducing additional passive components. On the other hand, it can improve load transition performance. Additionally a fixed switching frequency is maintained enabling easier passive components design. Moreover a minimal prediction horizon is utilized reducing the requirement on digital computational power. Simulations on a 270V/28V 100kHz 10kW Active-Bridge-Active-Clamp converter are carried out to verify the theoretical claims.
