A dual-active bridge (DAB) converter is provided. The DAB converter comprises a primary sub-circuit coupled to a direct-current (DC) input voltage, a first secondary sub-circuit and a second secondary sub-circuit, and a transformer isolating the primary sub-circuit from the first and the second secondary sub-circuits and comprising a predetermined number of turns. Each of the first and the secondary sub-circuits comprise a corresponding inductor; the first and the second secondary sub-circuits being configurable in a series mode and a parallel mode by switching configurations of a first, second and third transition switch; and the first and the second secondary sub-circuits providing an output charging voltage and an output charging current for charging an external device. A charging station comprising one or more charging poles, with each charging pole comprising one of more DAB converters is also disclosed.
