Abstract :
This paper presents a fault tolerant power electronics interface used in an hybrid PEM Fuel Cell generating system for transportation. A battery plays the role of an energy buffer on the DC link. Anti-parallel bypass diodes are used to isolate a defective fuel cell module. An interleaved boost converter with backup strategies realizes the electrical interface. The diode derivation circuit and the electrical converter can ensure uninterrupted power delivery and fault management. Simulations with degraded working modes for the fuel cell and power converter are presented and the diode bypass function is experimentally validated on a 20-cell 500 W PEM fuel cell stack.
