TY  - JOUR
AB  - By considering converter fundamental operating principles, the paper first derives a complete set of analytic expressions of theoverall power losses of a conventional Dual Active Bridge (DAB) bi-directional DC-DC converter under Dual Phase Shift (DPS)control. Expressions for conduction and switching losses in the electronic devices acting as the converter switches, and copperand core losses in the isolation transformer, are derived and accounted for in the DC-DC converter model. DPS control involvesmany more converter operating conditions, in comparison tothe more common single-phase-shift (SPS) control, which makes theanalytic power loss characterization of a DPS-controlled converter an arduous task. Subsequently and by employing thederivedanalytic converter power loss model with exemplary parameter values, the paper analyzes the efficiency of a high-fidelity fullhybrid electric vehicle (HEV) model that includes a DAB DC-DC converter, under a wide range of realistic driving conditions andconverter operation, including low- to high-speed driving, and converter DPS operation. Two popular hybrid powertrain energymanagement schemes, the Thermostat and Power Follower control strategies, are used to simulate the vehicle model to reinforcethe range of realistic vehicle operating conditions. The results show that in series HEV applications more accurate modeling ofDC-DC converter models than conventional constant efficiency models is required to predict converter losses, and also the fidelityin the characterization of converter losses can have a significant impact on the vehicle fuel consumption prediction.
