Power Switch Fault-Tolerant Control of a Floating Interleaved Boost Converter for Fuel Cell Electric Vehicle Applications

Résumé

Over the last decade, fault tolerance has gained a growing interest from the scientific community, particularly for power converters such as DC/DC converters. Generally, fault-tolerance refers to a fault-tolerant topology and/or control for power converters. Within the framework of this research work, a Floating Interleaved Boost Converter (FIBC) is used in order to meet the fuel cell vehicle requirements. In DC/DC converters, power switches ranked the most delicate components. The most common failures in power switch are Open-Circuit Faults (OCFs), gating faults and Short-Circuit Faults (SCFs). The loss of one leg in case of OCF or SCF (considering that the faulty leg is isolated before damaging the system) leads up to the drastic increasing of the fuel cell current ripple and consequently long-term degradations on the fuel cell. The purpose of this paper is to present an efficient Fault-Tolerant Control (FTC) in order to reduce drastically these degradations. The performances of the power switch FTC are given from experimental results between a fuel cell and a FIBC topology.
