“…However, when moving to threephase SAB (3p-SAB) converters, only a few papers about the operation of 3p-SAB converters could be found [17]- [19]. Paper [17] and [18] present the current and power equations under the basic operation when the active duty cycle keeps at 0.5. Paper [19] presents the discontinuous mode when the 3p-SAB uses a delta-wye transformer arrangement, but does not consider the comprehensive operational principles with the most common wye-wye transformer arrangement.…”

“…Even though three-phase SAB converters require more components, they show advantages over single phase SAB in four aspects. Firstly, the current stress would be reduced given the same power rating and it is advantageous for high power applications [18]. Secondly, as there are more phases, the DC currents would be smoother so that less DC capacitance is required [7], [17], [26].…”

Single Active Bridge (SAB) DC/DC converters are attractive options for unidirectional DC/DC conversion in future medium power generation applications, offering galvanic isolation and a diode-based output side. SAB DC/DC converters must be controlled by adjusting the active bridge switching duty cycle, unlike Dual Active Bridge (DAB) converters where the phase-shift angle control is normally used. This paper presents a comprehensive analysis of the operational principles of threephase SAB (3p-SAB) DC/DC converters that arise from different duty cycle operation ranges. Moreover, the converter performances such as transformer harmonic currents are analyzed and are compared between different input and output DC voltage conditions. Finally, an experimental validation using a small scale prototype is presented. Index Terms-Three-phase single active bridge DC/DC converter, operational modes, duty cycle control, performances.

This paper describes the development of a threephase interleaved soft-switched dc-dc converter suitable for plugin battery chargers in electric or hybrid car applications. Its architecture consists of three half-bridge converters ("phases") sharing the same input and the same output port. All phases operate with fixed 50% duty cycle, at the same frequency and with 120° phase-shift with respect to one another, so that current ripple at both the input and the output is minimized. Power control is performed by changing the operating frequency. With an appropriate design all phases will work with soft-switching (Zero-voltage switching, ZVS) and, by using "phase shedding", the converter's efficiency can be kept extremely high over very wide load range. The paper, after providing its design guidelines, illustrates the operation of a 1 kW three-phase interleaved soft-switched dc-dc converter prototype built as a proof of concept to demonstrate the capabilities of this architecture and shows the results of its bench evaluation. Special emphasis has been given to some aspects related to its control, realized using a digital controller specific for power conversion applications.
