摘要：With the conventional secondary phase-shifted (PS) control, a semidual-active-bridge (S-DAB) dc-dc converter suffers from low efficiency at light load in buck mode due to hard switching and high tank current. In order to avoid this phenomenon and extend soft-switching range, a hybrid control including the primary pulsewidth modulation plus secondary phase-shifted (PWM+PS) is proposed in this paper. Under the proposed hybrid control, all steady-state operation modes with distinctive features are identified and analyzed. Based on the operation range, power characteristics and switching behaviors in each mode, a minimum peak current control route is developed, which can enable the converter to work with low tank current and soft switching over the whole load range. A lab-scale S-DAB converter is implemented to validate the theoretical analysis, and experimental results reveal that the higher efficiency can be achieved using the proposed control route.
