The need for battery storage in applications using solar energy requires, in most cases, the use of topologies with bidirectionality and high-power density. The Dual Active Bridge converter meets all requirements in most applications and is a widely used topology.In this paper, a Dual Active Bridge converter for elevator applications has been analyzed and optimized. Firstly, a general overview of the converter is presented, and its different modulation strategies are discussed. Simulation tools have been used to optimize the system to find the optimum value of inductance to minimize transistor power losses. The converter has been implemented and tested under different values of inductances. Finally, the transistors bridge temperature has been compared depending on the implemented inductance, and an improvement in the system has been verified.
