Abstract
The power supply system is designed to allow for the determination that the system did not temporarily switch to a backup state due to a temporary voltage drop. [Solution] When the terminal voltage Vb of the battery 24 drops, the PU72 closes the backup switch 60. This puts the system into a backup state where power from the auxiliary power supply 80 is supplied to the inverters 32a and 42a. The PU72 sets the backup confirmation flag to "1" only if the backup state continues for a predetermined time. The PU72 transmits the backup confirmation flag to the reaction force main microcontroller 34a, which is capable of communicating with the outside.
