Claim Text:
1. A redundant power supply system providing rapid start of backup, comprising: at least one primary power supply which receives external power and is triggered externally to boot up to transform the external power to output a primary working power, and compares the primary working power based on an output comparison criterion at boot up time thereof to generate a first light load working parameter or a first heavy load working parameter; at least one secondary power supply which receives the external power and is triggered externally to boot up to transform the external power to output a secondary working power, and includes a voltage regulation and energy saving element in a power factor correction unit to perform charging and include a regulation potential, the secondary power supply comparing the secondary working power based on the output comparison criterion at boot up time thereof to generate a second light load working parameter or a second heavy load working parameter, and comparing the regulation potential based on a low voltage judgment criterion when triggered externally to shut down to get a shutdown mode and a standby working mode; in the standby working mode the secondary power supply being booted up for a short duration when the regulation potential is lower than the low voltage judgment criterion to charge the voltage regulation and energy saving element to make the regulation potential higher than the low voltage judgment criterion, and the secondary power supply being shut down when a transient working period is over; and a power integration panel which is electrically connected to the primary power supply and the secondary power supply, and includes a first start mode to receive the second light load working parameter from the secondary power supply to shut down the secondary power supply, and a second start mode to receive the first heavy load working parameter and the second heavy load working parameter respectively from the primary power supply and the secondary power supply so that the secondary power supply is booted up to transform the external power and output the secondary working power.
