Background technology
For some, need long-time hitless operation, highly reliable system, as base station communication apparatus, center exchange or routing device, watch-dog, server etc., often need highly reliable power supply, adopting redundant power design is an effective scheme realizing this high reliability power supply, in high-availability system, plays an important role.2 of redundant power one general configuration or a plurality of input power.When 1 input power breaks down, other input powers can come into operation at once, not the normal operation of interrupting device.This is similar to the operation principle of ups power: when civil power power-off, by battery, replace power supply.The difference of redundant power is mainly to be powered by different input powers simultaneously, and UPS is that an input power all the other input powers of powering are standby at any time, automatically switches whenever necessary.
Fig. 1 shows a prior art scheme.As shown in Figure 1, n (n >=2) input power has been shown in Fig. 1, and n diode D1, D2 matching with input power quantity ... Dn.Each input power connects respectively the anode of a diode, and with or door mode parallel connection export on power supply output bus.In this scheme, " input power 10
1", " input power 10
2" or " input power 10
n" simultaneously to power supply output bus 301 power supply, when one or more input power wherein breaks down while quitting work, remaining input power will be taken over fault input power and carry out work.Due to diode D1, D2 ... the pressure drop of Dn itself large (silicon diode is 0.6V～0.8V conventionally, and germanium diode is 0.2V～0.3V) can cause the voltage to the output of power supply output bus.Diode D1, D2 under the larger condition of electric current ... the intrinsic power consumption of Dn can increase rapidly, needs to increase heat abstractor and dispels the heat.Therefore the conversion efficiency of this scheme redundant power is lower, and the heat abstractor of increase is also unfavorable for the design of redundant power lightweight and miniaturization.
Fig. 2 shows another prior art scheme.Wherein, comprise source S, grid G, drain D.In when normal operation, the grid G driver output of controller is field effect transistor conducting, but loses efficacy and sent a telegraph stream when reverse at input power, and it can turn-off fast, and other input powers are taken over fault input power and worked on simultaneously.This programme has adopted the MOSFET pipe (conducting resistance is at a few m Ω conventionally) of low resistance, so power consumption is very low, does not need to increase heat abstractor, has also improved the conversion efficiency of input power.But each road input power of this scheme all adopts an independently controller, and input power 10
1with controller 40
1, input power 10
2with controller 40
2, input power 10
nwith controller 40
nmatch respectively, such design has increased the design cost of redundant power.Because the indoor design of MOSFET pipe has fly-wheel diode, therefore, when the voltage of indivedual input powers is high compared with the voltage of other input powers, can exists and pour in down a chimney phenomenon, easily damage input power.
And, redundant power in above-mentioned two kinds of prior art schemes adopts identical input power to realize redundancy conventionally, and in as special industry environment such as vehicle environments, due to the variation (conventionally having direct current 24V and electric main 220V) of input power, now the redundant power of prior art just cannot have been satisfied the demand.
