ABSTRACT:
A device for overvoltage protection of rectifier/inverter bridges employing gate-controlled solid-state switches without zero diodes is disclosed. To protect at least the solid-state switches of the rectifier/inverter bridge against overvoltages, the device incorporates one or two overvoltage protector units which are activated when the voltage between at least two protection connections exceeds the voltage across a storage capacitor of the overvoltage protector unit. Thus, a controllable switch connected in parallel with the storage capacitors is turned on when the voltage between two protection connections exceeds an excitation value and is turned off when the voltage falls below the excitation value, controlled by a control unit of the protector unit.
