Digital emulator and observer of multicell converter Original Research Article

This article presents the design of a digital real-time emulator dedicated to the simulation of four-level multicell converter. The design has been made using a new tool: the co-simulation. Co-simulation results are presented in this paper and an experimental setup has been realised on a FPGA in order to validate this new tool. In the final part, we present the test of an observation loop using this emulator.
