Abstract:
1. A Graëtz-bridge converter-rectifier comprising a plurality of terminals called AC terminals, fed with alternating current, and two terminals called DC terminals, adapted to feed an exterior circuit with direct current, rectifier arms (U 1 +, U 1 −, V 1 +, V 1 −, W 1 +, W 1 −, U 2 +, U 2 −, V 2 +, V 2 −, W 2 +, W 2 −) connecting each AC terminal to each DC terminal, a rectifier arm being situated between a single AC terminal and a single DC terminal, and multiple unidirectional electronic components, called unidirectional components, connected in parallel and connected on one side to the DC terminal by means of a conductive component set, called component set, and on the other side to the AC terminal; wherein the component set for at least one rectifier arm (U wherein the connection between the unidirectional components and the AC terminal is effected by a fuse set, that includes a fuse resistor, called fuse, for each unidirectional component connected on one side in series with said unidirectional component and on the other side to at least one fuse busbar connected to the AC terminal.
