Classification: CPC H  F  Y | IPC F  H

Claim 5:
6. A DC/DC converter circuit, comprising:
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,
wherein the control circuit is configured to, as a result of comparing one or both of a predetermined output voltage set value and a predetermined output current set value as the target supply power to a predetermined threshold value to determine whether the DC/DC converter circuit is in the high-voltage low-current output mode or in the low-voltage high-current output mode, connect the switching circuit to the rectifier circuit when the DC/DC converter circuit is in the high-voltage low-current output mode, and connect the switching circuit to the current doubler circuit when the DC/DC converter circuit is in the low-voltage high-current output mode.
