Patent ID: 11949260
Assignee: DENSO CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  B | IPC B  H

Claim 0:
1. A power supply system comprising:
a first route including a first power supply connected to a first load;
a second route including a second power supply connected to a second load;
a connection path connecting the first and second routes with each other, the connection path including:
a first inter-route switch disposed in the connection path, and
an inductance having a given inductance component connected in series to the first inter-route switch;

an abnormality determiner to determine if an abnormality has occurred in any one of the first route and the second route; and
a state controller to output a switch-off command to the first inter-route switch when it is determined by the abnormality determiner that an abnormality has occurred,
wherein the inductance component has a given value causing a time constant of a circuit composed of one of the first route and the second route in which the abnormality does not occur and the connection path not to allow a voltage of one of the first load and the second load disposed in the other one of the first route and the second route to decrease to less than a lower limit of an operating voltage of the one of the first load and the second load during a shut-off period, and
wherein the shut-off period starts from a time when it is determined by the abnormality determiner that an abnormality has occurred in any one of the first route and the second route to a time when the first inter-route switch enters a switched off state upon receiving the switch-off command from the state controller.
