AC/DC converter having single detectable input

Abstract

An AC/DC input power converter including only a single input cable such that a user will never have to switch cabling, regardless if the cable is connected to an AC voltage source or a DC voltage source.

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; and   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.   
   
   
       2 . The power converter as specified in  claim 1  wherein the detector comprises a circuit including an integrator configured to change the output state of said detector upon detection of the DC input voltage. 
   
   
       3 . The power converter as specified in  claim 2  wherein the detector comprises a solid state switch configured to detect the DC input voltage. 
   
   
       4 . The power converter as specified in  claim 2  further comprising a relay configured to pass the DC input voltage as a function of the integrator. 
   
   
       5 . The power converter as specified in  claim 1  wherein the power converter further comprises displaceable prongs configured to receive the AC input voltage and which are electrically coupled to the AC/DC converter, wherein the detector is configured to detect and respond to a position of the displaceable prongs. 
   
   
       6 . The power converter as specified in  claim 5  wherein the displaceable prongs are configured to be rotatable between a first position and a second position. 
   
   
       7 . The power converter as specified in  claim 5  wherein the detector is configured to selectively control the DC/DC converter as a function of the prongs' position.
