Description of the invention: [Technical field to which the invention pertains] - A backup system that specifically controls the power output architecture and is combined with a power supply to ensure the normal operation of the system. ~σ [Prior Art] If the computer equipment encounters power failure or power instability, it will cause the system to be abnormally closed or the data will be damaged. In severe cases, the body will be damaged, resulting in an incalculable loss. To avoid this situation, computer equipment "The supply of Un 翻 翻 翻 ( (Unintemipt Wei P_r Supply, UPS) 'and use the power provided by the conventional UPS system to continue the power supply for the power supply, in order to win the Na Jingzheng read the time of the deposit; and the conventional knowledge of the system is connected with the electric power supply. After flowing 7L 12 and the power factor correcting unit 13, 'at least one is controlled by a wave width control unit 15; " component 17 adjusts the converted power of a transformer 14, and passes through the back-end rectifying unit 16 to transmit, and conventionally The uninterrupted power system 6 is also connected to the city's power, and sequentially through the uninterrupted power, system 60 - AC / DC converter (10), - charging circuit 6 〇 4, a battery 6 〇 5, a boost = converter 6G2, by losing After the AC power is converted to DC power, the second / 05 charging 'When the city (four) force is not available, the DC power output from the battery (9) 5 is converted into AC power output to the AC power input terminal U of the power supply, so that the power failure = When the power is unstable, the power supply can still rely on the power provided by the uninterruptible power system 6: the conventional architecture needs to output power through the power supply, and the voltage ^ or "often caused by riding, For the silk, if the electric system is in operation, it will be replaced by the structure of the power supply, and the structure of the power supply has to be improved. Load; therefore, the conventional content [invention] ensures that the Wei supply 11 is inconsistent. The lack of improvement in the power of the power, the purpose of this fortune is to provide a backup system that can maintain the load working power when the power is off and the device is damaged. - a power backup system, the power backup secret system consists of - temporary power inspection system with 200908510 and - power rib replacement unit - the power reserve system is connected to at least the normal power supply system in the normal power supply system output When the power is abnormal, the power of the power backup system is connected to the unit to connect the singularity of the secret electricity, and when the money is normal, the power of the drive is provided by the normal system, and when the power is cut off, When the lightning problem is stable or the normal power supply system works abnormally, the action of switching the money supply system is generated, and the transient power supply system maintains the power supply to keep the load sustainable for a period of time. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The detailed description and technical contents of the present invention will now be described with reference to the following drawings: Referring to FIG. 2, which is a block diagram of an embodiment of the present invention, the present invention is a power backup system. The power reserve system is connected to at least the power check button. The normal state is: - the power supply H. The power supply 丨 has - the AC power input terminal u, the front end rectification unit 12 - the power factor correction unit 13. Transformer 14, - wave width control unit / switching element Π and - rear rectification unit 16, the power backup system consists of - transient power supply system 2 and -f force source switching unit 3, the power The source switching unit 3 is connected to at least the power supply 1 and the transient power supply system 2, and the power supply Wei 2 can receive the DC power input and convert it to the power source 3, the power source The selection of the switching unit 3 is normally powered by the normal power supply system, and is output via the power supply terminal 3 at least the voltage output terminal 31, and when the utility power supply is abnormal or the power supply supply is abnormal, the normal power supply system output is abnormal. The power source switching unit 3 switches and selects the temporary power supply system 2 to provide power for the temporary day f, and connects the power source switching unit 3 to immediately power off. Please refer to FIG. 3, which is a block diagram of a preferred embodiment of the present invention. The normal power supply system is a power supply H 1 '! The power source switching unit 3 includes an electric trip circuit %, a controlled by the electric rib surface 33 of the touch circuit 32, and the dragon output port Μ, and the transient power supply pure 2 includes - backup power The source 2〇 and the power transfer element 21, the power switch 33 is difficult to be secretly connected to the output of the secretary, and the voltage judgment circuit 32 determines whether the output voltage is normal, and the power is switched. The output of the switch 33 is driven by the voltage output terminal 31 to drive at least a load; the backup power source 2 of the transient power supply system 2 includes an AC power input terminal 11, an AC/DC converter 201, and a charging circuit 6 200908510 202, an energy storage component 203 and a switch 204, the AC/DC converter 201 and the power supply 1 can be connected to the AC power provided by the mains, and converted by the AC/DC converter 2〇1. The charging element 203 is charged, and one end of the switching switch 204 is switched between the AC/DC converter 201 and the energy storage element 203, and the other end of the switching switch 204 is connected to the power conversion unit 21 at the back end. The power conversion unit 21 is a DC/DC converter 211, wherein the switch 2〇4 is normally connected to the AC/DC converter 201. The power output by the AC/DC converter 201 is controlled by the switch 2 4 is transmitted to the DC/DC converter 211 and also transmitted to the charging circuit 2〇2 to charge the energy storage element 2〇3, and the switching switch 204 is connected and controlled by the power source switching unit 3; When the AC power supply provided by the utility power is interrupted, the voltage determination circuit 32 of the power source switching unit 3 detects the normal state supply and records the abnormality, and the employee-deactivated Vs controls the end of the power switch 33 to switch to The transient power supply system 2, the power switch 1 is immediately connected to the temporary, 4 power supply 2 DC / DC La II 211, and the switching signal Vs output by the voltage determination circuit 32 simultaneously triggers the switching of the backup power source 2G The switch tearing switch is connected to the energy storage 70 pieces 2〇3', and the power supplied by the energy storage element 2〇3 is supplied to the load after the power is supplied to the unit through the DC/DC converter; the wire power source switching list Illusion (4) If the power supply is damaged, the power source switching unit 3 cuts the transient power supply system 2, and simultaneously commands the switch Μ4 to switch to connect the energy storage 203' and the normally input AC power continues.
