The invention provides a direct current power converter and a working method thereof. The direct current power converter comprises a main control circuit, a power input circuit, a voltage stabilizingcircuit, a voltage switching circuit and a voltage output end, wherein the power input circuit provides power for the main control circuit, the voltage stabilizing circuit and the voltage switching circuit; the main control circuit obtains an input voltage of the power input circuit; the main control circuit transmits a control signal to the voltage stabilizing circuit according to the input voltage; the voltage stabilizing circuit outputs a voltage-stabilizing voltage to the voltage switching circuit according to the control signal; and the voltage switching circuit switches an output voltageoutput by the voltage output end. The working method provided by the invention controls a voltage-increasing adjusting factor and a voltage-reducing adjustment factor in the voltage stabilizing circuit according to the input
