  • Patent number: 11183839
    Abstract: Disclosed examples relate to a power conversion system configured to provide a power output from an arrangement of direct current (DC) power sources. One example power conversion system includes multiple power sources PV(n), n=1 to x, connected in a series. For each power source PV(n) for n=1 to x?1, the power conversion system includes an intermediate bidirectional voltage converter VC(n) connected to a first terminal of the power source PV(n), a first terminal of power source PV(x), and a second terminal of power source PV(1). Each intermediate bidirectional voltage converter VC(n) includes a first switch operable in a pulsed mode to boost a power output by power source PV(n) and a second switch operable in a pulsed mode to reduce a power output by power source PV(n). The power conversion system also includes a balancer VC(x) connected to the first terminal of PV(x) and to a load.

  • Patent number: 9577548
    Abstract: Embodiments related to the conversion of DC power to AC power are disclosed. For example, one disclosed embodiment provides a power conversion system, comprising a plurality of direct current (DC) power sources, a plurality of power output circuits connected to one another in a parallel arrangement, each power output circuit being connected to a corresponding DC power source to receive power from the corresponding DC power source and to selectively discharge power received from the corresponding DC power source, a power combiner configured to combine power received from the plurality of power output circuits to form a combined power signal, an output stage configured to convert the combined power signal into an AC signal or a DC signal, and a controller in electrical communication with each power outlet circuit and the power combiner to control the output of power by the power converter.
