1. A power converter, comprising:
- an input;
a DC/DC converter configured to receive a DC input voltage from the input and provide a first DC voltage to an output;
a AC/DC converter configured to receive an AC input voltage from the input and provide a second DC voltage to the output;
a detector configured to detect whether the AC input voltage or the DC input voltage is provided to the input and responsively enable or disable either the DC/DC converter or the AC/DC converter; and
wherein the detector comprises a circuit including an integrator configured to enable or disable either the DC/DC converter or the AC/DC converter upon detection of the DC input voltage.
