Abstract

The invention relates to a parallel power supply system module number control method based on a current-sharing standard difference matrix array and a minimum. A standard difference matrix between an actual current value and expected current-sharing deviation is built, and the module output current in a condition with the optimal current-sharing performance of the parallel power supply system is determined; then, through acquiring the output current of an online working power module in real time, a total load current value of the system is solved, the total load current value is divided by the module output current value in the condition with the optimal current-sharing performance obtained through former measurement, and the number of online operation power modules of the parallel power supply system is obtained; and finally, a parallel power supply system centralized controller controls the online power module number in real time, the system is ensured to constantly work in the optimal current-sharing performance condition, and through building a current-sharing standard difference matrix A=(sigmami)K*U in various load conditions, and the array and the minimum of A=(sigmami)K*U are calculated. The online power module number is dynamically adjusted in real time, the parallel power supply system is ensured to constantly work near at the optimal current-sharing working site, and the current-sharing performance is high.

Description

technical field [0001] The invention relates to a method for controlling the number of modules in a parallel power supply system based on the standard deviation matrix column of current sharing and the minimum, which is used to optimize and control the number of power supply modules running in parallel to achieve optimal current sharing performance. The method is also applicable to other electronic equipment running in parallel. Flow optimization control. Background technique [0002] High-power parallel power supply is a parallel output structure of multiple power modules. Due to a series of advantages such as strong compatibility, N+m redundant backup, strong reliability, high cost performance, low design difficulty, and easy management, it has become a large-scale solution. One of the preferred options for power output power supply design. Current sharing technology has become the core technology for parallel power supply of switching power supply modules. The current s...
