Design And Implementation Of Power Electronic Controller Based On FPGA

Modern power electronic devices face higher requirements in terms of equipment control real-time performance,switching frequency,and integration.Traditional serial power electronic controllers often cannot meet the requirements.With the continuous advancement of Field Programmable Gate Array(FPGA)technology and gradually develops into a programmable system-level chip,it gradually shows unique hardware parallel advantages in the design of digital systems,and realizes different levels based on hardware circuits The software function has become a new development direction of power electronic controllers,and at the same time,Electronic Design Automation(EDA)technology also brings design convenience for this kind of hardware implementation.Therefore,FPGA is a very promising technology for the field of power electronics.In this paper,we will study the design method and implementation process of FPGA-based power electronics controllers and verify them on an experimental platform,centering on the design theory of FPGA power electronics controllers.Following tips is the main work:Based on the research and application analysis of FPGA in the field of power electronic controller design,this paper derives the characteristics of power electronic controllers with FPGA as the core,and puts forward the guiding significance of FPGA all-digital power for the difficulties of FPGA design.Electronic controller design theory,and based on this theory,a three-level power electronic IP core library is built based on the theory.This paper designs high-speed uninterrupted sampling control state machine,nanosecond-level hardware protection mechanism and other auxiliary control task logic that FPGA often undertakes in power electronics practical engineering applications,and then designs a general auxiliary logic control board,which can greatly improve power electronic control System design efficiency.This paper Researchs the control theory of APF,and builds a simulation model and a T-type three-level power electronic application platform,and integrates the corresponding IP core library on the application platform by building blocks.The IP core realizes the control function and then verifies the feasibility of the proposed design theory with experimental results.In the same application scenario,the specific performance quantitative index comparison between the FPGA controller and the DSP controller is given,and the benefits of FPGA implementation are confirmed.
