A self commutating static converter having two main controlled rectifiers in series which are coupled to a d-c supply voltage and including two bypass rectifiers, one associated with each of the main rectifiers and means for forced commutation in which a circuit for recharging the commutation capacitor and for discharging the capacitor back into the d-c supply voltage including a controlled recharging rectifier which is arranged to be fired when the voltage exceeds a predetermined limit is provided to permit the converter to properly function when subjected to varying d-c supply voltages and large load currents. |
