Description

This report presents a step by step design procedure for a dual active bridge DAB converter which is connected to a DC link in the primary side and a supercapacitor module in the secondary side. The supercapacitors are used in energy storage systems (ESS) as an energy storage device ESD, in order to save and provide energy according load requirements. The characteristics of DAB allows the bidirectional power flow and a series inductance connected to the primary side of the transformer allows the controllability of the system. This inductance can be an external element or can be the leakage inductance of the transformer. This project aimed to control the active power flow without an external inductance. Limitation of time and interference issues have not allowed to complete the close loop design meeting the all requirements. However, several open and close loop results are presented obtained by simulation and others obtained using the experimental prototype.
