AC/DC converter having single detectable input
View Patent ↗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;
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.
2. The power converter as specified in claim 1 wherein the detector comprises a solid state switch configured to detect the DC input voltage.
3. The power converter as specified in claim 1 further comprising a relay configured to pass the DC input voltage as a function of the integrator.
4. The power converter as specified in claim 1 wherein the displaceable prongs are configured to be rotatable between a first position and a second position.
5. The power converter as specified in claim 1 wherein the detector is configured to selectively control the DC/DC converter as a function of the prongs' position.
6. 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 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 respond to a position of the displaceable prongs.
