Abstract: In a power supply system, a first route includes a first power supply connected to a first load. A second route includes a second power supply connected to a second load. A connection path connects the first and second routes at a connection point. The first power supply includes a voltage generator generating an operating voltage operating the first and second loads. The second power supply includes an electrical storage device charging based on power supplied from the voltage generator. A switching circuit includes a first switch having a diode component with an anode and a cathode being directed to the electrical storage device and the connection path, respectively, and is disposed between the connection point and the electrical storage device. A switch state controller outputs a switch-off command to the first switch when the electrical storage device is in the fully charged condition.

Abstract: A control apparatus includes a first determination section determining whether a power-supply voltage has decreased below a first threshold value, an interruption section interrupting a current flow to an inverter if the voltage has decreased below the first threshold value, a second determination section that determining whether the power-supply voltage has increased above a second threshold value, an interruption releasing section releasing the interruption based on the fact that the voltage has increased above the second threshold value, a count section counting the number of interruptions, a limiting section determining whether the decrease in the power-supply voltage is caused by a first factor of an electric rotating machine or a second factor, and limits the counting if the decrease in the power-supply voltage is caused by the second factor, and a third determination section determining whether the interruption is allowed to be released based on the number of interruptions.
