Background technology
At present along with the appearance of blade server, blade server is meant in the rack of functions such as I/O interface such as integrated network and power supply, heat radiation, management, inserts a plurality of cassettes (blade-like) server unit.These cassette server units are exactly usually said blade.Blade itself has parts such as processor, internal memory, hard disk, mainboard, is that with tower and difference rack-mount server functions such as I/O interface, power supply, heat radiation and management are all provided by the rack unification.A plurality of blades are all arranged, so in cabinet, not in the narrow space, how to lay minimum chipset, electronic package and interface arrangement in each cabinet.
The voltage regulator circuit of current blade server comprises that 3 normal voltage adjustment modules 2 are connected with power supply unit 1,3 standby Voltage Regulator Module 3 are connected with power supply unit 1, under the state that blade server is activated, one reference power supply of normal voltage adjustment module 2 output voltages is to circuit board 4, under the state that blade server is activated still under the holding state, the standby power of exportable voltage is to this circuit board 4.3 normal voltage adjustment modules and 3 standby Voltage Regulator Module are exported the voltage of 1 2V, 5V, 3V respectively.So under the situation that needs N magnitude of voltage, just need N normal voltage adjustment module 2 and standby Voltage Regulator Module 3 like this, cost increases and is difficult to connect up in the blade server narrow space like this.
Also by further improving, Voltage Regulator Module 2A is connected with power supply unit 1, switch unit 5 links to each other with Voltage Regulator Module 2A, under the situation of switch unit conducting, one end of switch unit is exported a reference power supply, not under the situation of conducting, the standby power output terminal accepts also to continue the power supply that the output voltage adjustment module is transmitted at switch unit.So still, need 3 Voltage Regulator Module and 3 switch units.Wiring still is difficult in the blade server narrow space.
Summary of the invention
The utility model is in order to solve above-mentioned weak point, a kind of voltage regulator circuit of blade server.
Practical newly by the following technical solutions in order to realize this: a kind of voltage regulator circuit of blade server, comprise power supply unit,
