Embodiment Construction

[0018] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] The structure of the high-speed real-time power parallel system of the present invention is as follows: figure 2 As shown, the system includes multiple power modules connected in parallel, and each power module includes a high-speed receiving module, a high-speed sending module, a current summing module and a current sharing control module. The sending module of the former power module is connected to the receiving module of the latter power module to form a ring communication structure and realize current summation and current sharing control. The high-speed receiving module and the high-speed sending module can be integrated into a high-speed transceiver module in practical applications.

[0020] Current summing modules such as image 3 Shown, including sampling circuit, analog-to-digital conversion circu...

Abstract

The invention discloses a high-speed real-time power supply parallel connection system which comprises a plurality of power supply modules connected in parallel and is characterized in that the power supply modules are sequentially connected through a high-speed transmit-receive module to form a communication loop, and each power supply module receives information sent by the previous power supply module through the high-speed transmit-receive module, integrates self information of the power supply module into information and sends the integrated information to the next power supply module. Self information acquisition of each power supply module and control of each power supply module are realized. Various control and instantaneous flow measurement for the power supply parallel connection system can be realized. The system is simple in hardware structure, digital signals are transmitted in a link, the transmission speed is fast, the real-time performance, interference immunity and flexibility are excellent, the error is small, and various functions are easy to realize.

Description

technical field [0001] The invention relates to the field of measuring electronic equipment, in particular to a power supply system. Background technique [0002] Parallel operation of power supplies can realize modularization and large capacity of power supply products, which is one of the development directions of power supply technology and the key to realize combined high-power power supply system. After parallel expansion of power supplies, on the one hand, it is necessary to take current sharing measures to realize current sharing control when power supplies are running in parallel, and on the other hand, it is necessary to measure the total current after parallel connection. [0003] At present, the measurement of current sharing control and current summation is mainly based on hardware circuits, such as figure 1 As shown, the slave machine sends the current information of the machine to the switchboard through the sampling circuit, and the switchboard receives the c...
