摘要： A DC/DC power converter 100 comprises three or more capacitors 120a-d connected in series between an output terminal 112 and a ground terminal 113, the three or more capacitors 120a-d being connected in series by means of two or more capacitor connection points 121a-c, and an input voltage switching unit 130a-130d configured to connect an input terminal 111 to one of a group of switching connection points 121a-c, 112, the group of switching connection points comprising the two or more capacitor connection points and the output terminal 112. With such a DC/DC power converter it is possible, for example, to convert a variable DC voltage at the input into a variable DC voltage at the output, wherein the voltage range of the output voltage is smaller than the voltage range of the input voltage.

摘要： Embodiments of this application disclose a photovoltaic power generation system, so that a voltage in the photovoltaic power generation system can be increased under a same power conversion condition, to reduce a current in the photovoltaic power generation system, thereby reducing energy consumption and reducing costs of the photovoltaic power generation system. The method in this application includes: a photovoltaic array, a direct current conversion unit, a bus unit, and an inverter unit, where there are one or more photovoltaic arrays; the photovoltaic array is configured to: convert solar energy into electric energy, in other words, generate direct current power, and output a direct current voltage; and the bus unit is configured to store direct current electric energy output by the direct current conversion unit or directly store the direct current electric energy output by the photovoltaic array, to increase a bus voltage in the first bus unit. An input voltage of the inverter unit is increased under the same power conversion condition, which can effectively reduce a direct current bus current in the photovoltaic power generation inverter system and correspondingly reduce an alternating current obtained after inversion by the inverter unit. Therefore, an electric energy loss in the photovoltaic power generation inverter system is reduced.
