Claims12
A power converter, comprising:
- a power bus;
- and
- a plurality of converter legs each connected to the power bus and each including a bus capacitor, a switching stage coupled to the bus capacitor and means for isolating the bus capacitor from the power bus in the event of a fault in the bus capacitor.
An inverter for operating a switched reluctance machine, comprising:
- a DC power bus;
- and
- a plurality of inverter legs each coupled to the DC power bus and each including a DC bus capacitor, a switching stage coupled to the DC bus capacitor and means for isolating the DC bus capacitor from the DC power bus in the event of a fault in the DC bus capacitor.
