Abstract: Systems and methods for providing DC-DC power converter topologies are described. In at least one embodiment, a DC-DC power converter comprises a primary sub-circuit coupled to a fixed or variable DC input voltage, a first secondary sub-circuit and a second secondary sub-circuit, a transformer isolating the primary sub-circuit from the first and the second secondary sub-circuits, the transformer comprising a predetermined number of turns, 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.

Abstract: 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.

Abstract: A co-planar transformer is provided. A dual-active bridge converter comprising the co-planar transformer is also provided. The co-planar transformer comprises a printed circuit board with a plurality of primary windings and a plurality of secondary windings. The number of primary winding turns is equal to the number of secondary winding turns. The plurality of primary windings and the plurality of secondary windings are provided on the same printed circuit board in an interleaving configuration, wherein the interleaving is provided horizontally across the printed circuit board. Other embodiments of co-planar transformers include two or more such printed circuit boards with interleaved plurality of primary and secondary windings.

Abstract: An LLC resonant converter is provided. The LLC resonant converter includes a primary sub-circuit coupled to a direct-current (DC) input voltage and a first secondary sub-circuit and a second secondary sub-circuit. The primary sub-circuit includes a resonant tank, that includes a combination of a resonant inductor, a resonant capacitor and a magnetizing inductor. The LLC resonant converter also includes a first transformer isolating the primary sub-circuit from the first secondary sub-circuit and a second transformer isolating the primary sub-circuit from the second secondary sub-circuit. The first and the second secondary sub-circuits are configurable in a series mode and a parallel mode by switching configurations of a plurality of transition switches, and the first and the second secondary sub-circuits provide 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 LLC resonant converter modules is also disclosed.
