The main power supply 11 includes a protection unit 110, which has protection functions such as overvoltage, overcurrent, and low voltage. When one of the plurality of pluggable modules 3 is hot swapped, the main cause The power supply u has abnormalities such as overvoltage, overcurrent, and low voltage. The protection unit 110 causes the main power source u to enter the protection mode to stop the normal power supply; and when the protection unit 110 detects that the main power source u can work normally, the main power supply is released. The protection mode of 11 causes the main power supply u to supply power normally. The detailed structure of the protection unit 1 (7) is familiar to those skilled in the art, and a detailed description thereof will be omitted herein. An isolation element 16' may be disposed between the main power source u and the modules 3 to prevent the output current from flowing back to the main power source n in reverse. The auxiliary power source 13 is used to supply power to the mold cylinders 3 during the normal power supply interruption of the main power source U. The auxiliary power source 13 can be selected to be the same as the main power source - the input power source (input power source 2) can also use an independent input power source. The independent input power source can also be any external power supply device (such as 220V power supply) or an ac/dc device built into the storage system, but the output voltage should be the same as the output voltage of the main power supply 11. A separate component 16 can be disposed between the auxiliary power source 13 and the modules 3, and the core prevents the output current from flowing backwards to the auxiliary power source 13. The control unit 15 is connected to the auxiliary power source 13 for whether or not the main power source u can be normally powered to send a control signal to the auxiliary power source 13 to turn off or turn on the source 13. The main power supply 11 can normally supply the lightning bar. There are two situations: 1. The main power supply 11 enters the protection mode and stops the normal power supply; 2. The main recognition, - the output voltage fluctuation of the main power supply 11 exceeds the threshold level. Situation, control home view; ^ Gan & Track system early I5 choose to detect one or two of the above situations, that is, if the control unit 1 <; shop (1), ^ ^ early 兀 * 15 detected the main When the power supply 11 enters the protection mode 2 to stop the normal power supply, or / and the output voltage of the control unit S15_ to the main power supply U fluctuates beyond the threshold level, a start control signal is issued, and the auxiliary 8 201024983 power supply 13 is activated. If the control unit 15 When it is detected that the main power supply u can restore the power supply, the shutdown control signal is issued, and the auxiliary power supply 13 is turned off. The main power supply u can resume the power supply, including two situations: 1. The main power supply 1丨 has been released from the protection mode and is normally powered; The main power source 11 is releasing the protection mode. According to the actual situation, the control unit 15 selects to detect one or both of the above situations. In addition, in the preferred embodiment, the control unit 15 is disposed on the main The protection unit 11 of the source u is referred to. The second figure is a power supply device for hot swapping the support storage system according to the second embodiment of the present invention. In the second embodiment, the control unit 15 transmits The input terminal is connected to the output end of the main power source 11 and is connected to each module 3 via the isolation element 16, and the output terminal is connected to the auxiliary power source 13. The control unit 15 is independent of the first embodiment. The control unit 15 in the protection unit ιι of the power supply u. The other structure of the second embodiment is the same as the structure of the first embodiment, and thus the detailed description thereof is omitted here. Please refer to the third figure, which is a In the third embodiment, the power storage device 1 is configured to include a first control unit (5) and a second control unit 152, and a control unit thereof. 151 is set in the protection unit m of the main power source 11, the second is == is an independent component, and its input terminal is connected to the output end of the main power source 11. The first control 16 is connected to each module 3' The output terminal is connected to the auxiliary power source 13. 2.

When the main power supply u can be normally powered, the auxiliary power supply 13 can be turned off, that is, the first control single fantasy 51 and Second control When the element 152 meets the control condition at the same time, the auxiliary power supply can be started or turned off. Referring to the fourth figure, the hot plugging operation is shown as a type of support library hot swap according to the embodiment of the present invention. The power supply device is adapted to a connection diagram of a hot-swappable storage system, such as a disk array (RAm) device, a computer or an information processing system, including a plurality of pluggable modules. The pluggable modules are a plurality of hard disks 3, and the hard disks 3 may be SATA hard disks or SAS hard disks, etc. A power supply device that supports hot swapping of the storage system is used to supply power to the hard disk. The hard disk 3, the main power source 11 and the auxiliary power source 13 each include a power conversion module for converting the input power to meet the working needs of the hard disks 3'. In this embodiment, the hard disks 3 The working power is +5 V. The main power supply 11 and the auxiliary power supply 13 are all connected to the +12 V DC input power supply. The output end of the main power supply 11 is connected to each hard disk 3' via the isolation element 16 to prevent the output current from being reversed. Flow into main power supply h, auxiliary power supply 13 The output terminal is connected to each hard disk 3'. The control unit 153 is like a dual-mode comparator of the type LM393, whose non-inverting input terminal is connected with a threshold level, and the inverting input terminal is connected to the output end of the main power supply 11 via the isolation element. 16 is connected to each hard disk 3', and the output terminal is connected to the auxiliary power supply 201024983 source 13. When the main power supply 11 is normally powered, the voltage of the inverting input terminal of the control 罝-W ancient shape saponin 153 is 冋; 5 mesh 1 ^The threshold level is, for example, + (7V 'control unit 153's ==' auxiliary power supply 13 is in the off state, hot insertion of a hard disk 3 to the hot-swappable storage system, when the system is left _疋 153 detects that the hot-plug operation causes the output voltage of the main power source 11 to decrease below a threshold level, for example, +4.7V, that is, when the voltage of the anti-decrement terminal of the control shirt 1 is lower than the _ input terminal +4_7V, the control Unit 1S3 rounds up and powers up the eleventh column, such as $ terminal to two-level, sends a start control signal, activates the auxiliary power supply 13; if the control unit calls 贞_main power u can restore power supply, then the shutdown control signal is issued , _ auxiliary power supply 13. The control unit 153 is a double-pressure comparison. For the sake of clarity, only the part of the control unit 153 during the hot insertion operation is shown in the fourth figure. It can be understood that the control unit 153 can also detect the hot extraction. When the operation causes the main power supply 11 to increase (four) voltage rise, the output voltage rise threshold level of the visible main power supply U is, for example, +5.3 V, and the control unit detects (4) that the hot pull-out operation causes the output power of the main power supply u to rise. When the threshold level is higher than the threshold level, for example, +5 3v, the start control signal is issued, and the power source 13 is activated. The structure and principle are similar to the above example of the hot plug operation, which is not described here. Please refer to the fifth figure. The method of the present invention includes the following steps: Step 1. Turn on the power supply device of the present invention to support the hot swap of the storage system; Step 2: Power the main power supply to a plurality of pluggable modules; Step kick 3: When the pluggable module is plugged and unplugged, the output voltage of the main power supply fluctuates; Step 4: The control unit detects whether the main power supply can be normally supplied, and if yes, proceed to step 2 'if no, Then proceed to step $; 201024983 zero (4) 5. The control unit sends an open control signal to the auxiliary power supply to turn on the auxiliary power supply; Step 6: Auxiliary power supply to the plurality of pluggable modules; Step 7: The control unit detects whether the main power supply is The power supply can be restored. If yes, proceed to step 8. If not, proceed to step 6; and the step control unit sends a shutdown signal to the auxiliary power supply, and turns off the auxiliary power supply. Step 2 » Step 4: The main power supply can be normally powered. In two cases, the main power supply enters the protection mode to stop the normal power supply; second, the output power of the main power supply exceeds a threshold level. The control unit may choose to speculate one or both of the above depending on the actual conditions. In step 7, the main power supply can be restored.
