Abstract
A power failure protection system is provided for a solid state drive. In an embodiment, the system includes: power converters; a stand-by power converter; a power switch array including power switch pairs; and a power control complex programmable logic device. The power control complex programmable logic device monitors power failures of the power converters; when a power failure of a particular power converter is detected, configures a power level for the stand-by power converter, the configured power level corresponding to the failed power converter; and controls a target power switch pair corresponding to the failed power converter such that an operation voltage generated by the stand-by power converter is applied to an internal component.
