Recent developments in real-time analogue simulation of high power electrotechnical systems

About fifteen years ago, the challenge of simulation in power electronics and electrical engineering was to predict and understand the global behaviour of various topologies of power converters and electrical machines. Nowadays, with the growing interest in real-time, simulation offers controlling, monitoring, servicing power and testing new control laws. Different approaches had been proposed for real-time simulation, In this paper, an approach based on analogue simulation is presented. The real-time analog simulator comprises current conveyors, analog operators and real switches. New operating principle and experimental results are described
