Abstract
An electrical conversion system includes an inverter arranged according to a multilevel type topology with k arms and a command device for cut-off against an electrical overload, connected to a set of first intermediate lines to measure a first intermediate continuous voltage. The cut-off command device is configured to determine a fault by detecting if the first measured intermediate continuous voltage is outside of a nominal voltage variation range [Vmax, Vmin] of the first intermediate voltage and to transmit a generalised opening command signal for an opening of the electronic commutation switches of each arm when the fault is determined.
