Latest Patents

The supplied information lists one patent for Xin Qi: “Photovoltaic System and Circuit Protection Method for Photovoltaic System.” The invention describes a photovoltaic system with an active protection switch, a DC-DC conversion circuit, and a controller. When reverse current reaches a specified threshold, the controller sends a breaking instruction to turn off the switch. If the switch does not turn off effectively within a preset duration, the controller regulates the converter’s input voltage to remain at or below a first voltage threshold. This approach provides an additional protective response when the initial switching action is unsuccessful.
