The invention concerns a reversible current rectifier, for connection to part of a polyphase network and to a continuous bus comprising a plurality of rectifier cells each rectifier cell including a rectifying device and a on-way electronic switch connected in anti-parallel with the rectifier device, the rectifying devices of different cells being arranged so as to form one rectifier. Each rectifier cell comprises means for controlling the electronic switch of the cell arranged to control the latter in closure after detecting a conduction of the rectifying device of the cell so as to enable current to be returned to the network. The control means are arranged to receive a signal external to the cell, for controlling the opening of the electronic switch, derived from another rectifier cell.
