Abstract: An electronic power convertor which has a plurality of rectifiers arranged in a bridge connection is provided with a pulse generator and with connecting members in the circuit between the pulse generator and the rectifiers. Connecting members in the connection between the pulse generator and the rectifiers are controlled by control circuits which, in response to a blocking signal, render the connecting members inoperative, so that control voltage is no longer supplied to the rectifier from the pulse generator directly through the connecting members. However, the control circuit also acts to continue the supply of control voltage to one of the rectifiers which are conducting at the time that the blocking signal is initiated and to the corresponding rectifier of the same phase of the bridge, so that these two rectifiers will conduct and form a by-pass circuit. In case of deblocking of the rectifier, each commutation group of the bridge is deblocked separately by the normal control pulse for the proper rectifier of the group acting in the by-pass circuit.
