Research on Real-time Simulation System of Three-phase Inverter Based on Multi-FPGA
The real-time simulation system is an important tool for analysis,design and experimental verification of three-phase inverter and its control algorithm.The existing commercial real-time simulation systems are expensive,and the requirements of multiple time scale real-time simulation between components and system are hard to meet.This paper designed a real-time simulation system for three-phase inverter based on multi-FPGA.The dy-namic process model of IGBT switch was constructed by the strategy of segment fitting.Based on IGBT models and system state equation,three-phase IGBT bridge arm model,LC filter and load model were constructed respectively.The multi-FPGA architecture was used to realize multiple time scale real-time calculation of models,and the upper computer software was designed to realize model parameters issuance and simulation waveform display.Simulation ex-perimental results show that in the designed real-time simulation system,the simulation steps of IGBT model and sys-tem are 20ns and 10μs respectively,the multiple time scale real-time simulation of three-phase inverter IGBT parts and system is realized.
