Zusammenfassung:	The embodiment of the invention discloses a DC/DC converter and an output reverse connection detection method and device. The method comprises the following steps: acquiring a voltage signal of a positive electrode output end of the DC/DC converter; determining an output reverse connection detection result of the DC/DC converter according to the obtained voltage signal; and on or off of the DC/DC converter is controlled based on the output reverse connection detection result. The connection state of the output end of the DC/DC converter is judged by acquiring the voltage signal of the positive electrode output end of the DC/DC converter, and the on or off of the DC/DC converter is controlled according to the connection state of the output end of the DC/DC converter, so that when the output end of the DC/DC converter is reversely connected, the reverse connection of the output end of the DC/DC converter can be detected in time, and the DC/DC converter is controlled to stop working; an external low-voltage powe
