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.
