The Dual Active Bridge (DAB) is a reliable and efficient converter that is able to provide bi-directional power transfer as well as galvanic isolation. An ac-ac DAB can control both active and reactive power flow. The present work introduces a combined feedback/feedforward current control system, utilizing the calculated and measured converter currents translated into the dq reference frame, to control the output power. The system was simulated in PLECS using a step input for active and reactive power to demonstrate the control algorithm's ability to track the dq currents and provide the necessary output power.
