Abstract :
A 20 kVA direct DC/LFAC dual active bridge (DAB) power converter projected for operation at 100 kHz with insulated gate bipolar transistor (IGBT) switches is presented. It has dual-angle, constant-frequency phase shift control, and is soft switched in a large part of the output V-I plane. It also has a high performance digital control system. The topology and its properties are presented. The control strategy and regulation of the loop are examined. Experimental results are shown for both a small-scale model and a full-scale converter
