INSTRUCTIONS: [Technical field to which the invention pertains] The present invention relates to a backup electric hybrid system, in particular, a backup power supply; [Prior Art] Due to the power demand, the electric equipment of the type of equipment, such as the type 4 computer, is used in computer equipment such as airplanes, and the power supply of the powerful and complex Weicheng Weicai is used to check the power supply switching.

At present, we have developed a lot of backup power supply secrets 1 to strengthen the backup or fault tolerance, such as - with the AC and DC power input of the standby power supply, in the United States, please see the 11/G22, 795, double The backup source of the power source input is for the sewing machine to let the electric wire be in use—when the power source is interrupted, the DC power can be continuously output to the normal operation of the electrical equipment. The main backup power unit of the previous backup type is electrically connected by the new mode. Take the 1+1 backup power supply system as an example. In theory, the two main power units set the average distributed load current to drive the electric appliance. The equipment is in normal operation. However, in many practical applications, any main power unit may have an aging or output impedance difference, etc., which cannot uniformly bear the same power. If it is forced to provide the same power, it is easy for the power unit to survive. Scale _ electrical equipment is operating normally, and the main power unit is forced to fully bear the output power and exceed the load, greatly reducing the service life of the backup power supply system, thus developing the current load distribution technology of the main power unit (Current Sharing Technique) to solve the above problems, as shown in U.S. Patent Application No. 20060273740. The current load technology device detects the DC power of the output 1 and returns a signal to the main power unit to adjust the output power according to the detected current signal, so that the output power of the side main power unit occurs. Abnormality will suppress the output of 5 dc power, and the power supply of the other main power unit will depend on the best power output, so that all the main power is suddenly destroyed. For example, the life of the H backup power supply system is reduced and the supply system is reduced. The system provides the lion's _ad, type P〇Wer provides the output (four) depends on the different power levels, The service should be issued by the system. Each power supply has a single power = ^ group to integrate the power level to provide the best power output. Touching the power, ensuring that each of the main power unit is designed with β and & balance mode for output power. Most of the needles are used in the backup power supply system and the power is always required. Standing power, with the increasing recovery of electrical equipment 'still development _ can be installed in the shutdown state of the standing power list = = 1; in the state, you can operate alone. Therefore, each standing power single force is the main power ί early? Under the condition that the output is forced to exceed the load and the life of the power supply meter 70 is reduced, the power supply can be supplied under normal conditions, and even the load can be turned off to cause the power unit to suddenly be powered off. The internal parts of the electrical equipment rely on the loss of the sub-components of the standing power to cause damage. [Summary of the Invention] Mai is the main purpose of the present invention, in addition to balancing the main power unit output of each backup power supply, straight /; lt_electricity makes the main power output with the best quality, the needle S load increases Side. The backup power units also balance the output of the standby power to achieve the overall backup power supply, optimize the output power, and prevent the power supply of the main power unit or the standby power unit from being interrupted to avoid important equipment jumping. To achieve the above objective, the present invention provides a backup power supply system including an N+M power supply, the power supply being electrically connected to at least one external power source to convert the power output. The power conversion unit inside the power supply has at least a standing power unit of a normal output power and a main power unit that provides power in a power-on state; each power supply unit is electrically connected to at least one power integration control unit. The power conversion unit 13317714 unit Chun Weiyuan silk out of the conversion power combined with the ^; the power unit and the standing power unit and the power integration unit between the frame ^, / ί balance I yuan and - the second power balance unit, the The first-power balance unit and the second power balance are reduced early and the balance is assigned to the balance. The force is determined by the load ratio of each power supply === [Embodiment] 2 The details and technical know-how are as follows: Block and "2nd picture" are the backup power supply of the present invention_路方Ϊ@+Μ Λ,本发赖-峨Power supply The system should use the Ν+Μ group power supply 10, 2〇, which is the power supply (1) required for the sum of the electrical power loads of the electrical equipment operation; the number of power supply 20 damage.
