  Parallel current sharing of switching power supplies is becoming more and more popular?

  In the design and development of power supplies, high-power power supplies are used more and more widely. The power supply is a switching power supply, which is widely used in the power communication industry. In recent years, high-power switching power supplies have also become popular in parallel current-sharing power supply planning. Compared with traditional high-power switching power supplies, what are the advantages of this parallel current-sharing distributed switching power supply system planning? Why is the parallel current sharing of high-power switching power supplies more and more popular? This article will work with you to conduct an in-depth analysis and understanding of this issue.

  Today's power supply industry is developing rapidly. In terms of reality, the planning and use of distributed power systems have gradually become the main stream and will be one of the directions of future power development. Compared with the traditional centralized power supply, the distributed power supply system has many advantages. For example, the sensitivity is relatively higher, and the power density is greatly improved. In terms of appearance, The size and weight of the power supply are smaller and lighter. The electrical stress of the power semiconductor device of the power module is reduced, which improves the high reliability of the system, and can accomplish redundancy well. The biggest feature is that it has fundamentally solved the problem of diversified commodity varieties, and the number of commodity varieties is decreasing, which facilitates the implementation of standardization standards.

  In addition, the high-power switching power supply is set by parallel current sharing method, and it can also maintain a certain redundancy. The so-called redundancy actually refers to the backup power supply module. For example, if 3+2 converter modules are connected in parallel, and 3 of them are used to supply the current required by the load, the remaining 2 high-power power supplies are redundant modules. If we choose this form, the advantages will naturally be magnified. When the module in operation shows a problem, the backup module is put into operation, so even if there are n units of the module in operation, the power system can ensure that 100% of the load is supplied. Current. In addition to increasing the redundant power of the system, the use of this parallel current sharing technology can also complete heat exchange, that is, to replace the failed module of the system under the condition of ensuring the uninterrupted power supply of the system. In the current demand trend of the power supply system, there are two aspects, one is high reliability, and the other is high power, both of which are closely related to the parallel operation of the switching power supply. The advantages of parallel operation of switching power supply are in three places: one is that it can be used to sensitively expand the capacity of the switching power supply system; the other is that it can form a parallel redundant system to improve the reliability of operation; the third is that it has a very high system that can be repaired. Function, when a single module is defective, it can be easily hot-plugged, replaced or repaired.

  Above we have analyzed the working principle, definition, working status and other aspects of high-power switching power supply. The main demand for high-power switching power supply parallel technology in the power system and communication system is increasing. However, in the process of parallel setting of high-power power supplies, there is still a question that requires engineers to do one by one, that is, the current sharing method between switching converter modules is required to ensure the uniform distribution of electrical and thermal stress between the modules. Prevent one or more units from operating in the current limit condition. Through these analyses, everyone has some understanding of why the parallel current sharing of high-power switching power supplies is becoming more and more popular.
