Machine emulator: Power-electronics based test equipment for testing high-power drive converters

Today the development process for power electronics includes modeling, simulation, control design, implementation in hardware and finally the test of the hardware at a suitable test bench. In case of drive systems, changing to a different type of machine or to a different rating of the machine requires only relatively few modifications of the control and its parameters. Nevertheless, at least the prototype has to be tested under conditions close to reality. In many cases even the test of each converter and its control is required before shipping to the customer.
