“…With the symmetric structure, the HF oscillation problem can be alleviated. The circuit schematic in [310] mainly consists of two T-type full bridge cells and an LCL resonant network. With the proposed PWM control, full range ZVS and wide range zero circulating current can be achieved.…”

“…Among several examples, are highlighted: the three-level DAB converter with five control degrees of freedom [13], the neutral point clamped DAB converter [14], the multilevel DAB converter utilizing an LCL filter at the transformer side [15], and the dual bridge series resonant converter [16], which, compared to the traditional DAB, has as main features two resonant tanks and a tappedtransformer to increase the soft-switching range of the converter. Moreover, in [17], the feasibility of connecting two DAB converters in parallel is studied, so that the efficiency of the system is optimized for different voltage and power demand levels.…”

This paper addresses the comparison and validation of different modulations for an isolated dc-dc dual active bridge converter (DAB), namely, Duty-Cycle Modulation, Single Phase Shift (SPS), Dual Phase Shift (DPS), Extended Phase Shift (EPS) and Triple Phase Shift (TPS). Given the DAB’s applicability in a wide variety of power electronics branches, several control strategies are being studied to improve its efficiency, by mitigating circulating currents and reactive power. Regardless of the chosen architecture, appropriate modulations must be adopted, assessing which one presents the better cost-benefit ratio. This simulation-based analysis aims to investigate the DAB performance when controlled by the above-mentioned modulations and operating with a nominal power of 3.6 kW. Thus, simulation results show that only SPS, DPS, and TPS are considered suitable, while Duty-Cycle Modulation has time limitations during power transfer and EPS is more appropriate for dynamic power applications.
