Investigation of ZVS condition for dual-active-bridge converter using dual-phase-shift modulation

This paper investigates the operation principle of Dual-Active-Bridge (DAB) converter using Dual-Phase-Shift modulation. All eight operation modes are examined in order to find out the limitation for Zero Voltage Switch (ZVS) achievement. Some constraints are established to identify the ZVS region....

Description
Summary:This paper investigates the operation principle of Dual-Active-Bridge (DAB) converter using Dual-Phase-Shift modulation. All eight operation modes are examined in order to find out the limitation for Zero Voltage Switch (ZVS) achievement. Some constraints are established to identify the ZVS region. Simulation results affirm that if the modulation is taken inside the region, lower switching dissipation could be attained. Especially, at the boundary of that region, the switching devices could obtain not only ZVS but also ZCS characteristic.
