Abstract
The invention belongs to the field of redundant power supplies and provides a control method for synchronous starting of a redundant power supply and the redundant power supply. One power module in the redundant power supply is set as a starting guide module, same delayed starting time is set for other power modules in the redundant power supply, the starting guide module receives a starting signal command firstly and then outputs starting triggering signals to the other power modules, the other power modules receive the starting triggering signals and then are started synchronously after the same delayed time, so that the power of the redundant power supply at the moment of starting reaches the sum of power of the multiple power modules, the output power of each power module cannot be increased during synchronous starting, and potential safety hazards cannot be caused.
Description
Technical field
The invention belongs to redundant power field, particularly relate to control method and redundant power that a kind of redundant power synchronously starts shooting.
Background technology
Redundant power is for a kind of power supply in server, industrial computer (Industrial PC:IPC) security monitoring etc., is made up of, carries out load balancing by chip controls power supply two duplicate power modules.
In general n+1 redundant power product, generally the maximum start power of power supply is only allowed to be no more than the maximum rated power of separate unit power supply when AC or PS-ON starts shooting, but at present along with under server more carrys out to rise high more and more harsher requirement to system dimension/performance and power, a lot of system its can exceed the rated power of the separate unit power module that power supply can provide at the power opening moment, even require that n+1 redundant power application scenario booting moment power can reach the summation of n platform power module power.
Usually to realize the mode that the parallel operation of 1+1 redundant power opens machine and have following two kinds:
First kind of way: realize 1+1 parallel operation by the over-current protection point of adjustment separate unit power module and open machine at full capacity, but this kind of mode has following shortcoming:
Because separate unit power module over-current protection point need be adjusted to more than two times of rated power; as the power supply of 3000W; its over-current protection point point must be transferred to more than 6000W; it is 110% ~ 130% safety grounds requirement that this point cannot meet power supply to over-current protection point; more fatal is; after separate unit power module over-current protection point tunes up, if power supply because of certain reason long-term work in
overloadduring state, because power supply OCP point is adjusted too high, when the time of overwork is longer, power source internal stresses of parts can cannot meet the demands and cause power supply mortality to damage, so kind mode can exist great Quality Safety hidden danger
The second way: power module is designed to invariable power mode approach, invariable power state is entered when output load exceedes the rated power of single power module, when another power module output voltage gets up, load completes parallel operation by two power module shareds and opens machine function at full capacity, but in current low-voltage, big current, great potential safety hazard was there is in powerful server power supply application time upper, such as, if when system is short-circuited, because this kind of design possesses very strong output loading capability, its load fan-out capability sustainable existence always, energy accumulation can be caused, when energy accumulation reaches the wire rod that a timing can cause in system, the devices such as semiconductor, because temperature rise continues too high overheated severe compromise such as grade on fire.
