PROBLEM TO BE SOLVED: To provide an auxiliary power unit capable of avoiding an increase in a dark current attributed to the provision of a feedback circuit.SOLUTION: An auxiliary power unit for a vehicle is provided with a power storage part connected in parallel with a DC power source to which a voltage is applied from the DC power source when an ignition switch is turned on, a voltage boosting part for boosting an output voltage of the power storage part and supplying it from an output terminal to an external load and a voltage boosting control part with a voltage terminal to which the voltage boosted by the voltage boosting part is applied for controlling the operation of the voltage boosting part on the basis of the level of the voltage applied to the voltage terminal, and includes path control means provided in the middle of a path to connect the output terminal of the voltage boosting part to the voltage terminal of the voltage boosting control part for connecting/disconnecting the path according to the on/off of the ignition switch.

    【課題】フィードバック回路を設けたことに伴う暗電流の増加を回避できる補助電源装置の提供。【解決手段】直流電源と並列に接続され、イグニッションスイッチがオンされた場合に直流電源から電圧が印加される蓄電部と、蓄電部の出力電圧を昇圧して出力端子から外部の負荷へ供給する昇圧部と、昇圧部が昇圧した電圧が印加されるべき電圧端子を有し、この電圧端子に印加された電圧の高さに基づいて昇圧部の動作を制御する昇圧制御部とを備える車両用の補助電源装置において、昇圧部の出力端子と昇圧制御部の電圧端子とを接続する経路の中途に設けられ、イグニッションスイッチのオン/オフに応じて、経路を接続/遮断する経路制御手段を備える。【選択図】図1
