A protection arrangement for an inverter having fuses connected in series with its d-c inputs is disclosed. In particular, in one form of the arrangement, an electronic voltage monitoring device is provided for monitoring the input d-c voltage to the inverter at the connection points of the inverter inputs and the fuses. If the voltage monitored by the monitoring device falls below a predetermined level, the monitoring device delivers a protection signal to the control unit of the inverter directing the latter to release firing pulses for extinguishing the valves in the valves branches of the inverter. |
