REDUNDANT POWER SUPPLY SYSTEM
First Claim
1. A redundant power supply system in which a predetermined power is supplied via a first DC-DC converter to a first battery and a first load of a primary system, and the predetermined power is supplied via a second DC-DC converter to a second battery and a second load of a secondary system independent of the primary system,the redundant power supply system comprising:
- a first switching element interposed between the second DC-DC converter and the second battery;
a first diode connected in parallel to the first switching element and configured to perform rectification in a direction from the second battery toward the second DC-DC converter; and
a control section configured to turn off the first switching element when the second battery is in a first state where a stored power amount thereof is equal to or larger than a predetermined first threshold value, and to turn on the first switching element when the second battery is in a state other than the first state.

Abstract
The redundant power supply system, in which a predetermined power is supplied via a first DC-DC converter (DDC) to a first battery and a first load of a primary system and the predetermined power is supplied via a second DDC to a second battery and a second load of a secondary system independent of the primary system, includes: a first switching element interposed between the second DDC and the second battery; a first diode which is connected in parallel to the first switching element and performs rectification in a direction from the second battery toward the second DDC; and a control section which turns off the first switching element when the second battery is in a first state where a stored power amount thereof is not smaller than a predetermined first threshold value, and turns on the first switching element when a state other than the first state is assumed.
