Research on Real-time Multi-rate Simulation of High Frequency Converter

Abstract

In order to solve the problem that simulation accuracy and simulation flexibility is difficult to take into account in real-time simulation of high frequency converter, a real-time multi-rate simulation method based on FPGA+PC is proposed. This method fully demonstrated the simulation principle of multi-rate co-simulation system and modeling method, and the process of hardware architecture design implementation. In this paper, a high frequency two level voltage source converter is selected for real-time multi-rate simulation test. Take off-line accurate simulation results as benchmark, we demonstrated comparison of simulation waveform, simulation error and simulation error between multi-rate co-simulation platform and PC real-time simulation platform. The result shows the validity of this multi-rate real-time simulation platform.
