In a pulse generator of the type in which a plurality of pulse forming networks are charged from a common supply and discharged into one, or more load circuits, a common valve is arranged to protect the circuit against reverse voltages developed in the pulse forming networks due to load mismatching. As shown, pulse forming networks 3A, 3B are respectively charged from a D.C. supply 1 via a common inductor 2 and separate charging diodes or thyratrons D1A, D1B to twice the supply voltage. The pulse forming networks are respectively discharged into a magnetron load R1 when the appropriate hydrogen thyratron T1A, T1B is triggered. A protective thyratron or diode D2 becomes conductive via valves D1A, D1B in the event of either pulse forming network attaining a reverse charge due to mismatching of the load R1. The unwanted energy may be dissipated in resistor R2, or this component may be replaced by an inductance as described in Specification 832,122.
