Design of FPGA-based emulator for series multicell converters using co-simulation tools

When high dynamic performances are desired, multicell converters are an option, but they may require extra control loops. However, cost reduction does not allow using additional sensors, and low cost estimators and observers have to be developed. Field-programmable gates arrays (FPGAs) with high sampling frequency seem to be able to perform such functions. The aim of this paper is to show how co-simulation helps designing such estimators and predicting their performances.
