<P>PROBLEM TO BE SOLVED: To provide a DC/DC converter that can prevent a DC bus voltage from rising and improve reliability of a device connected to the DC bus. <P>SOLUTION: The DC/DC converter comprises a controller which performs switching control, and supplies a power from a battery to a DC load connected to the DC bus by the switching control. The controller starts the switching control for widening a switching pulse width gradually when detecting that the DC bus voltage becomes lower than or equal to a predetermined voltage while the DC/DC converter is being stopped, and performs the switching control with the pulse width corresponding to an output setting voltage after detecting output current of the DC/DC converter. <P>COPYRIGHT: (C)2012,JPO&INPIT |
