Electrical converter with bypass safety

Electrical converter, comprising a plurality of conversion modules, the conversion modules comprising:

• input nodes connectable to a respective set of secondary windings of a transformer,
• a DC bus in direct current, having a positive pole conductor and a negative pole conductor,
• a rectifier connecting the input nodes to the DC bus, comprising a plurality of rectifier elements,
• an inverter connected to the DC bus,
• output nodes, wherein output nodes of distinct conversion modules are connected to each other,
• a bypass circuit arranged between the inverter and the output nodes, wherein the bypass circuit is configured to switch between an operating state, in which the output nodes are connected to the inverter, and a bypass state, in which the output nodes are connected to each other,
• a crowbar element, controllable to connect and disconnect the positive and negative pole conductors of the DC bus,
• wherein the rectifier comprises a plurality of fuses, each placed in series with a respective rectifier element of the rectifier.
