[Prior Art] If the computer equipment encounters a power outage or power instability, it will cause the system to shut down abnormally or the data is damaged. 4, and in severe cases will damage the body, resulting in an incalculable loss, in order to avoid this situation, the power supply of the computer equipment can be connected to the conventional Unintemiptable Power Supply (UPS), and use the knowledge constantly The power provided by the electrical system allows the power supply to continue to maintain the computer equipment to strive for the normal storage and shutdown time of the computer equipment; and the connection structure of the conventional uninterruptible power system and the power supply is shown in the figure. When the power is normally supplied, the power supply has an AC power input terminal n to obtain AC power. After a front end rectification unit τ 12 and a power factor correction unit 丨3, at least one switching element 17 is controlled by a wave width control unit 15 to adjust a transformer. The converted power of μ is output through a back-end rectifying unit 16, and the conventional uninterruptible power system 60 is also connected to the local power, and sequentially passes through an AC/DC converter 601 of the uninterruptible power system 60. Charging circuit 6〇4, a battery 6〇5, a boosting circuit 603, and a DC/AC converter 602, by converting the input alternating current into direct current The battery 605 is charged, and when the power in the city cannot be obtained, the DC power outputted from the battery 6〇5 is boosted and converted into an AC power output to the AC power input terminal of the power supply, so that the power failure or the power is unstable. The power supply can still operate for a period of time relying on the power provided by the uninterruptible power system 60; however, the conventional architecture needs to output power through the power supply, and the voltage sudden change or voltage instability often causes the power supply Damage, if the power supply is damaged by abnormal input power, even if the uninterruptible power system starts to operate to replace the mains as the power source of the power supply, the power supply has been damaged and cannot drive the load properly. Therefore, the conventional architecture also needs to be improved' to ensure the power supply when the power is abnormal! The output of I is normal. SUMMARY OF THE INVENTION In view of the above-mentioned shortcomings to be improved, the primary object of the present invention is to provide a backup system that can maintain load operation power when power is off, power is abnormal, or the power supply is damaged. The power backup system of the present invention is composed of a transient power supply system with a 1341162 - and - power source switching unit, and the "power backup system is connected with at least a permanent power system". The normal electricity (4) output power dissimilar material, the power source of the power backup New Zealand = the connection of the Jing Mi wire and the riding wire, and the drive of the regular wire is selected when the system is operating The power of the load, when the power is off, the voltage is unstable, or the operation of the towel power supply system is abnormal, the action of the power supply system is switched __, and the power supply system is selected to maintain the power supply for a period of time. [Embodiment] The detailed description and technical details of the present invention will now be described with reference to the following: FIG. 2 is a block diagram of an embodiment of the present invention.援纯' The power fiber brand is connected at least to the __ normal power supply. Material ^ Wei supply wire 1, the Wei supply wire 1 has - AC power input end ΓΓ ', 2 j rectification early 7L 12, - power factor correction unit 13. A transformer 14, a bandwidth control unit 15, a switch 7L, and a back-end rectification unit 16, the power backup system being composed of a transient power supply system 2 and a power source switching unit 3, The power source city unit 3 is connected to the power supply 1 and the transient power supply system 2, and the transient power supply system 2 can receive the DC power and convert it to the power source switching unit 3, and the power source is switched. The selection of the normal state of the single 疋3 mountain system is powered by the normal power supply system, and is outputted through the power source switching unit terminal to the electric _3 〗 〖3, and the normal power supply is caused when the electricity and electricity county abnormality device 1 is damaged. When the system output is abnormal, the power source switching unit 3 The selected transient switching power supply system 2 is temporarily provides power so that the power source of the switching unit 3 is connected not to a power off immediately. FIG. 3 is a block diagram of a preferred embodiment of the present invention. The normal power supply system is a power supply unit 1, and the power source switching unit 3 includes a voltage contact circuit 32, and a voltage is determined at 4 voltages. The power switching switch 33 of the circuit 32 and the voltage output terminal, the power supply system 2 includes a backup power source 2 () and a power conversion unit 21, and the power switch switch is normally connected to the power supply. ^ 丨 output, and judged by the voltage, 32 touches its output voltage is normal, and by the power supply switch%% of the conduction and output of the voltage output terminal 31 to drive at least a load; the transient power supply system 2 The power source, 20 includes an _AC power input terminal n, an AC/DC converter plus, a charging circuit 6 1343162 202, an energy storage component 203, and a switch 2〇4, the AC/DC converter 201 and the The power supply 1 can also be connected to the AC power provided by the mains. After the AC/DC converter 201 is converted, the charging circuit 202 charges the energy storage element 2〇3, and one end of the switch 204 is switched and connected to the The DC/DC converter 201 is connected to the energy storage component 203, and the other end of the 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 When the 204 is normally connected to the AC/DC converter 201, the power outputted by the AC/DC converter 201 is transmitted to the DC/DC converter 211 through the switch 204, and is also transmitted to the charging circuit 2〇2. The energy storage component 203 is charged, and the switch 204 is connected and controlled by the power source switching unit 3; therefore, when the AC power provided by the utility power is interrupted, the voltage determination circuit 32 of the power source switching unit 3 detects the normal state.
