description To provide a power supply device capable of suppressing the influence of loads connected to other phases when one phase becomes overcurrent.SOLUTION: A power supply device includes a bridge circuit including a first phase arm, a second phase arm, and a third phase arm, a first phase current detection portion that detects a first phase current, a second phase current detection portion that detects a second phase current, a third phase current detection portion that detects a third phase current, and a control circuit that switches the first phase arm, the second phase arm, and the third phase arm. The control circuit stops the first phase arm when the control circuit detects that the first phase current is an overcurrent, and stops the second phase arm when the control circuit detects that the second phase current is an overcurrent, and stops the first phase arm, the second phase arm, and the third phase arm when the control circuit detects that the third phase current is an overcurrent.SELECTED DRAWING: Figure 3 【課題】1つの相が過電流となった場合に、他の相に接続されている負荷が影響を受けることを抑制できる電源装置を提供する。【解決手段】電源装置は、第1相アーム、第2相アーム及び第3相アームを含むブリッジ回路と、第1相の電流を検出する第1相電流検出部と、第2相の電流を検出する第2相電流検出部と、第3相の電流を検出する第3相電流検出部と、第1相アーム、第2相アーム及び第3相アームをスイッチング動作させる制御回路と、を含む。制御回路は、第1相の電流が過電流であることを検出した場合に、第1相アームを停止させ、第2相の電流が過電流であることを検出した場合に、第2相アームを停止させ、第3相の電流が過電流であることを検出した場合に、第1相アーム、第2相アーム、第3相アームを停止させる。【選択図】図3
