“…In this condition, there is no circulating power among the MV cells, but only power exchange between the MV and LV sides. Consequently, the equation (4) can simplified to (5), where ϕ is the phase-shift angle between the MV cells and LV cell.…”

Abstract-The modular Smart Transformer (ST) is composed by several basic converters rated for lower voltage and power. In this paper the quadruple active bridge (QAB) is used as the basic block for the modular ST. In this application, the efficiency and cost are the most important design parameters. Therefore, the paper focus on the design of the converter, with the aim to optimize its efficiency, taking the cost into consideration. To do so, the losses of all components are carefully modeled and a computer-aided design is used, where an algorithm to calculate the losses and cost is developed, allowing to perform multi-objective optimization. Additionally, Silicon IGBTs and Silicon Carbide MOSFETs are considered for the design and the performance of the converter using both semiconductors technology is compared. Experimental results obtained for the optimized 20 kW QAB converter has shown an efficiency of 97.5%.

“…The basic module of the DC/DC stage is based on an isolated DC/DC converter, implemented normally using the Dual Active Bridge (DAB) converter [13], or the Series Resonant Converter (SRC) [14]. An additional approach is the use of multiwinding-based topologies, such as the quadruple active bridge (QAB) [15] as a basic cell.…”

“…The presence of power converters introduces conduction and switching losses whose evaluation is not easy: power converter losses depend on the SST configuration and the strategies implemented to control the converters. Some work on SST losses and efficiency evaluation has been carried out to date; see [8], [9], [26]- [29]. Since it is assumed that the model implemented in OpenDSS includes MV and LV filters, loss calculations account also for filter losses.…”
