Provided is a DC/DC converter circuit configured to achieve high efficiency both during low-voltage high-current output and during high-voltage low-current output, and an electric propulsion power source. The DC/DC converter circuit includes: a primary-side circuit configured to convert DC power from a DC power source into a pulse voltage; an isolation transformer configured to transform the pulse voltage while isolating the pulse voltage; a secondary-side circuit connectable in a switching manner by a switching circuit to one of a rectifier circuit for a high-voltage low-current output mode or a current doubler circuit for a low-voltage high-current output mode; and a control circuit configured to perform connection switching control of the switching circuit so as to establish, depending on target supply power, connection to the rectifier circuit in the high-voltage low-current output mode, and connection to the current doubler circuit in the low-voltage high-current output mode.
