Abstract

Real-time simulation for power electronics needs high-speed data processing and sampling, but most real-time simulation systems, such as dSPACE, can't meet the high-speed demands. Lyrtech's VHS-ADC, a high-speed signal processing system based on FPGA, is configured with multi-channels A/D, D/A and GPIO port, seamless interoperability with MATLAB, which has been applied widely in communication, audio, video and radar high-speed signal processing fields. However, VHS-ADC doesn't support real-time controller modeling. By constructing real-time control models including PI, PWM, Limiter and Reset-integrator model, this paper constructs a high-speed real-time simulation platform suitable for power electronics field. Further, the PWM-based Boost converter experiments prove the feasibility of real-time simulation by the rebuilt system, with Boost's switching frequency 100 kHz and its cycle 10μs. At frequency 100MHz, the corresponding simulation cycle is no more than 300ns, much less than switching cycle. Compared with TL494's waveform, it is proved that, as a novel way, VHS-ADC can support flexibly modeling process in real-time simulations with significant performance.
