High-Speed Real-Time Simulation for Power Electronic Systems (original) (raw)

SIMULATION, 2008

Abstract

ABSTRACT Real-time simulators have been used as an aid to power system design for many years. Over time, scaled-down physical models and analog computer-based simulators have given way to real-time simulators based on digital technology. Another trend has been the need for shorter and shorter frame times for these digital real-time simulators. Modern power electronic systems use highfrequency Pulse-Width Modulated (PWM) controllers. Indications are that frame times of 2 μS are needed for PWM switching frequencies of 10 KHz. As frequencies increase further it is possible that frame times of less than 1 μS may be required.
