Title:
POWER FEED CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/105905
Kind Code:
A1
Abstract:
A power feed control device (10) comprises an element unit (52), a voltage conversion unit (30), and a control unit (16). The voltage conversion unit (30) performs: a first conversion operation for stepping up or stepping down a voltage applied to a first conductive path (41) and applying the output voltage to a third conductive path (43); and a second conversion operation for stepping up or stepping down the voltage applied to the third conductive path (43) and applying the output voltage to the first conductive path (41). The element unit (52) is allowed to flow current therethrough to the power path (80) side and is enabled to block the current flowing therethrough to the electricity storage unit (92) side. The control unit (16) causes the voltage conversion unit (30) to stop or causes the voltage conversion unit (30) to perform the second conversion operation when the supply of power from a power supply unit (91) to the power path (80) is not in a failure state but in a normal state, and causes the voltage conversion unit (30) to start the first conversion operation when the supply of power from the power supply unit (91) to the power path (80) is brought into the failure state.
