  • Voltage converter
    Patent number: 9584023
    Abstract: A voltage converter for determining whether input power is DC power or AC power includes a power input terminal, an AC to DC converter, a switch and a DC detector. The AC to DC converter converts AC power into a DC output voltage when the input power is AC power. The AC to DC converter includes a brown-out detector, for disabling the AC to DC converter when a voltage of the input power is smaller than a predefined voltage. The switch passes DC power when the input power is DC power. The DC detector determines that the input power is DC power and turns on the switch when the voltage of the input power is within a predefined voltage range, and determines that the input power is AC power and turns off the switch when the voltage of the input power is not within the predefined voltage range.
