In a cycloconverter including an intermediate d-c link, a controlled rectifier and a inverter having main thyristors in a bridge circuit with bypass diodes in a bridge connected antiparallel thereto, a quenching circuit including a quenching thyristor and a commutating capacitor is connected parallel to each bridge arm, there being provided for each two bridge circuits having a common main lead a common commutating capacitor and at least one common damping capacitor, the latter connected parallel to a bridge arm to reduce the current dependence of the commutation voltage present at the commutating capacitor.
