Abstract
In accordance with embodiments of the present disclosure, a voltage rectifier may include an alternating-current-to-direct-current (AC/DC) converter configured to convert an alternating current (AC) source voltage to a first direct current (DC) voltage and a direct-current-to-direct-current (DC/DC) converter configured to convert the first DC voltage to a second DC voltage for delivery to a load of the voltage rectifier, wherein the DC/DC converter is configured to operate in a plurality of operating modes in response to a failure of the AC source voltage. The plurality of operating modes may include a first hold-up mode in which a gain of the DC/DC converter is a first gain and a second hold-up mode in which the gain of the DC/DC converter is a second gain.
