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.

Abstract translation: 用于确定输入电力是DC电力还是AC电力的电压转换器包括电力输入端子，AC-DC转换器，开关和DC检测器。 当输入电源为交流电源时，交流 - 直流转换器将交流电转换成直流输出电压。 AC到DC转换器包括一个欠压检测器，用于当输入功率的电压小于预定电压时禁用AC到DC转换器。 当输入电源为直流电源时，开关通过直流电源。 直流检测器确定输入功率为直流电，并且当输入功率的电压在预定的电压范围内时接通开关，并且当输入的电压被确定为输入电源是交流电源并且断开开关 电源不在预定义的电压范围内。
