Fault tolerant inverter or controlled rectifier system
First Claim
1. A fault tolerant inverter or controlled rectifier system comprising:
- a first leg including at least one switch device;
a spare leg including at least one spare switch device;
a spare leg connect switch associated with the spare leg and the first leg;
a fault detection sub-system configured to detect a fault in the first leg and to output a signal on detection of a fault in the first leg; and
a leg selection control sub-system configured to receive the signal output by the fault detection sub-system and to control operation of the spare leg connect switch in accordance with the output signal from the fault detection sub-system such that on detection of a fault the spare leg may be activated to take over the operation of the first leg.
