  "textContent": "This application discloses a photovoltaic power generation system, a photovoltaic inverter, and a direct current combiner box, and relates to the field of photovoltaic power generation technologies. The photovoltaic power generation system includes a protection switch and a plurality of DC-DC converters. Each DC-DC converter includes a direct current bus, a DC-DC circuit, and at least one input interface. The input interface is configured to connect to a photovoltaic unit. The photovoltaic unit includes at least one photovoltaic module. The input interface is connected to the direct current bus by using the protection switch, the direct current bus is connected to an input end of the DC-DC circuit, and an output end of the DC-DC circuit is an output end of the DC-DC converter. The protection switch includes a release and a switch mechanism that are connected in series. The release is configured to: when a short-circuit fault occurs on a line in which the release is located, control the switch mechanism to be disconnected. By using the photovoltaic power generation system, the photovoltaic unit and the line can be effectively protected when a short circuit occurs on the photovoltaic unit or the line.",
