1. A power converter comprising:
a power factor correction circuit having an electrical interface with four interface conductors, the power factor correction circuit being configured to:
convert an input single-phase electrical power to a first DC electrical power while operating in a single-phase input mode, wherein
an active phase of the input single-phase electrical power is received in parallel through a first conductor and a second conductor of the four interface conductors; and
a return phase of the input single-phase electrical power is received in parallel through a third conductor and a fourth conductor of the four interface conductors; and
convert an input three-phase electrical power to the first DC electrical power while operating in a three-phase input mode; wherein
a first phase of the input three-phase electrical power is received through the first conductor of the four interface conductors;
a second phase of the input three-phase electrical power is received through the second conductor of the four interface conductors;
a third phase of the input three-phase electrical power is received through the third conductor of the four interface conductors; and
the return phase of the input three-phase electrical power the fourth conductor of the four interface conductors; and
a controller configured to control the power factor correction circuit to:
operate in the single-phase input mode in response to a first command received via a control signal; and
operate in the three-phase input mode in response to a second command received via the control signal.
