Abstract:
A DC-DC converter includes a protection function for handling a reverse connection state, and a protection function for handling a predetermined abnormality other than a reverse connection state, while reducing conduction loss. The DC-DC converter includes a first protection circuit unit, and a switching element on a first conductive path of a high-voltage side switches to an OFF state upon a predetermined abnormal state being detected to prevent a current from flowing into a voltage conversion unit. Furthermore, a reverse connection protection circuit unit and a switching element, on a third conductive path between the voltage conversion unit and a reference conductive path, is configured to switch to an off state if at least a low-voltage side power supply unit is in a reverse connection state, preventing a current from the reference conductive path. Thus, a current is prevented from flowing toward a power supply that is improperly connected.

Claim (Index 9):
The DC-DC converter according to  claim 1 ,\n wherein a plurality of the voltage conversion units that step down a DC voltage applied to the first conductive path and output the resulting voltage to the second conductive path are provided in parallel between the first conductive path and the second conductive path, the first conductive path includes a shared input path that is electrically connected to a high-potential side terminal of the primary-side power supply unit, and a plurality of individual input paths that branch off from the shared input path and are respectively connected to the voltage conversion units, the second conductive path includes a plurality of individual output paths that are respectively connected to the plurality of voltage conversion units, and a shared output path to which the plurality of individual output paths are commonly connected and that is electrically connected to a high-potential side terminal of the secondary-side power supply unit, and the first protection circuit unit includes a plurality of the second switching elements that are respectively provided on the individual input paths, and the individual input paths are individually switchable to an OFF state and an ON state.
