AI Technical Summary
Technical Problem
Existing power supply systems in vehicles are prone to malfunctions due to noise interference, which can cause the fault detection circuit to malfunction, leading to unintended switching of power supply sources.
Method used
A power supply device with a control unit that switches a first switch unit to the off state and then returns it to the on state when a predetermined return condition is satisfied, thereby reducing the likelihood of malfunctions caused by noise interference.
Benefits of technology
The power supply device effectively minimizes the risk of malfunctions by ensuring that the power supply is restored to the on state when noise-induced errors occur, maintaining a stable power supply to the vehicle system.

Abstract
A power supply device (10) is included in a vehicle system (100) comprising a first power supply unit (90), a second power supply unit (91), a conductive path (80) provided between the first power supply unit (90) and the second power supply unit (91), and a load (70) electrically connected to the conductive path (80). The power supply device (10) has: a first switch unit (81) that is provided in a first conductive path (80E), of the conductive path (80), between the first power supply unit (90) and the load (70); and a control unit (83) that controls the first switch unit (81). After switching the first switch unit (81) to the OFF state, the control unit (83) causes the first switch unit (81) to return to the ON state when a first return condition is satisfied.
