An electric multimode power converter module includes an AC/DC converter, including a first AC port; a DC/AC converter, including a second AC port; a DC/DC converter, including a DC port; a controller; and a communication bus interconnecting the converters. The controller includes a hardware configuration port and sets the module in the following states, based on the value read from the configuration port: a first state in which the module transfers power between the first AC port and the DC port, a second state in which the module transfers power between the DC port and the second AC port, and a third state in which the module transfers power between the AC ports and the DC port. A power supply system includes a shelf device including at least one compartment, and an electric multimode power converter module as mentioned above is inserted in the at least one compartment.
