Abstract: A power generation system, a power converter, and a switch assembly. The plurality of positive input ports and the plurality of negative input ports are configured to electrically connect the switch assembly to an external direct current source, and the switch assembly is electrically connected to the power device through a trace on the circuit mainboard. The switch assembly includes a plurality of first pins and a plurality of second pins, the plurality of first pins are located in a first region, the plurality of second pins are located in a second region, the first region and the second region are stacked in a first direction. The controller is configured to send a switch-off signal to the switch assembly when the external direct current source or the power device is faulty. The power converter provided can resolve a problem of a short circuit occurring during condensation.

Abstract: Example power converters and detection methods are described. One example power converter includes a control device, a plurality of wiring terminals, a power conversion circuit, and a plurality of temperature detection devices. The control device is configured to: when an absolute value of a difference between a temperature value of one wiring terminal in the plurality of wiring terminals and a first reference temperature value is greater than or equal to a first temperature difference threshold, output a signal indicating that an abnormality occurs in the plurality of wiring terminals. In this application, a relative change of a temperature of one wiring terminal relative to another wiring terminal can be directly determined based on temperature values of the plurality of wiring terminals, thereby quickly determining, based on a magnitude of the relative change, whether there is an abnormal temperature rise caused by loose connections in the plurality of wiring terminals.
