Abstract

The invention discloses a general power electronic module distributed closed-loop control method based on an FPGA (Field Programmable Gate Array), which aims at overcoming the defects that the central control time sequence of the existing large-scale power electronic converter is disordered and the load is easy to overload, and improves the control bandwidth of a system through distributed control based on the FPGA. The converter is enabled to stably operate under a closed-loop control algorithm, and the concept of modularization is realized. And local control is executed through the slave computer, so that the response speed of the system is further improved, an abnormal working condition can be responded more quickly, and effective protection is provided for the whole system. The method is low in cost and easy to understand and implement, and can be applied to large-scale modular converters such as DAB and MMC.

Description

technical field [0001] The invention belongs to the field of industrial control computer and system manufacturing, and in particular relates to a distributed closed-loop control method for a general power electronic module based on FPGA. Background technique [0002] High reliability and low cost are always the development direction of power electronic converters, and an important method to improve reliability and reduce costs is to manufacture and function standardized modules. The concept of Universal Power Electronics Building Blocks (PEBB) was proposed by the US Navy Office in 1997, it was defined as a general power processor and a systematic approach with modular configuration, scalable voltage and current rating, as well as low cost and high reliability. [0003] With the increasing demand for medium-voltage converters and the limitation of space in society, power density and high efficiency have gradually become the development direction of general power electronic m...
