Abstract

See full text

A backup power circuit is provided. The backup power circuit includes a backup power branch array that includes N backup power branches that are coupled in parallel; and each backup power branch include a capacitor component and a unilateral conductive element, where the unilateral conductive element is configured to cut off a current path between capacitor components in the N backup power branches that are coupled in parallel, so that when some backup power branches are short-circuited, it can be ensured that backup power functions of other backup power branches are not affected, and backup power effects of the backup power branches are improved.
