摘　　要：电力电子领域的实时仿真对速度要求非常高,目前主流的通用实时仿真平台难以满足要求。VHS-ADC是一种基于FPGA的高速数字信号处理平台,在通信、音视频、雷达信号处理等领域得到了成功的应用。基于FPGA的高速数字信号处理能力,不失为构建高速仿真平台的一个新思路。基于这一思想,完成Boost变换器单周控制的实时仿真实验。实时仿真周期低于300ns,远小于变换器的开关周期10μs。实时仿真波形与TL494芯片控制波形作对比,证实了基于VHS-ADC建立高速仿真平台的可行性,该系统具有良好的实时性与通用性,且成本低于通用仿真平台。Real-time simulation for power electronics requires a very high speed, but most real-time simulation systems today can not meet the high-speed demands. VHS-ADC, a high-speed signal processing system based on FPGA, has been applied widely in communication, audio, video and radar signal processing fields. Based on the high-speed signal processing ability of VHS-ADC, a novel way to construct the high-speed real-time simulation platform comes out. Based on this idea, the OCC （one cycle control） Boost converter experiment was finished. The simulation cycle is no more than 300ns, much less than switching cycle lOlLs. Compared real-time simulation waveform with TL494＇s, it has proved the feasibility of constructing high-speed real-time simulation platform based on VHS-ADC, and the platform has outstanding real-time quality and applicability, meanwhile costs lower than general simulation platform.
