| Abstract | ||||
| This paper is aimed at examining the performance of H-bridges supplying fault-tolerant Permanent magnet machine in the aircraft fuel pump under short circuit condition. A significant DC component flows in the windings with a subsequent of saturation and higher iron losses, which possibly deteriorates the performance of the fuel pump. Expressions are derived to predict the inverter current during the fault. Also, the paper discusses all the possible remedial actions and highlights the most suitable one. | ||||
