1. A system for controlling a direct current, DC-DC converter, comprising:

  • a microcomputer for deriving an input limiting current value by dividing an input limiting power value by an input voltage value;

    a conversion circuit for scaling the input limiting current value to a limiting voltage value;

    a voltage control circuit for deriving a control voltage value based on an output voltage value and a reference voltage value and defining the limiting voltage value as a control voltage limiting value; and

    a current control circuit for generating a pulse width modulation (PWM) control signal based on the control voltage value.
