The cascade voltage and current controllers used to control the phase shift between the secondary and primary sides, the optimizer used to minimize the inductor peak current cause the efficiency to increase. One of the big challenges in the triple phase shift optimization is selecting and implementing the optimizer. The common optimizer used in the triple phase shift control of the dual active bridge is the Lagrange multiplier optimizer. This optimizer has been designed and implemented together with a look-up table optimizer because the Lagrange multiplier optimizer is not applicable in the wide range of the device application requirements.

SIMBA Simulation has been used for the following purposes:

1. To evaluate the thermal losses on the primary and secondary sides (conducting and switching losses) with Python.
2. Redesign the DAB parameters.
3. Implement and validate the voltage and current controllers.
4. Implement and validate the DAB optimizer.
5. Create the data for the optimizer (lookup table).
