Title
Modulation scheme to improve the efficiency for low load operating points for a dual active bridge DC/DC-converter
Abstract
The traditional phase shift modulation for the dual active bridge DC/DC-converter has the disadvantage of losing zero voltage switching (ZVS) at low load operations. This paper proposes a novel modulation scheme which enables the use of ZVS at low load conditions with a constant starting current and other advantages such as completely linear behavior at low loads and higher robustness against parameter tolerances.
