Portable AC-DC power converter and on-board power supply management device

A system comprising:

• a portable AC-DC converter comprising:
• an AC-DC conversion unit;
• an AC power plug connected to an input terminal of the AC-DC conversion unit;
• and
• a connector connected to an output terminal of the AC-DC conversion unit, wherein the connector comprises a DC output interface and a conductor physically arranged on the DC output interface;
• and
• an on-board power supply management device comprising:
• an on-board connector comprising a plurality of contacts, wherein the DC output interface is connected to the on-board connector, and wherein the connection of the DC output interface with the on-board connector causes the conductor to mechanically short-circuits the plurality of contacts on the on-board connector;
• and
• an on-board control unit configured to generate a trigger signal in response to the mechanical short-circuit of the plurality of contacts to operably connect and/or disconnect an on-board electrical equipment and an on-board power source, and wherein the trigger signal is generated independent of detection of an electrical fault condition.
