Real Time Monitoring for a Five-Level Double-Boost Power Factor Controller Including Post-Fault Reconfiguration

Résumé

A five-level power factor correction topology with fault-diagnosis and fault-tolerant capabilities is proposed and analyzed. This structure is derived from the well-known threelevel one-pole double-boost including double-stacked redundant and low storage energy flying capacitor cells. Two fault-diagnosis strategies are presented. The first one directly operates the monitoring of the voltages across the flying capacitors, detecting and localizing the faulty switch by means of two sensors. The second one is based on indirect voltage vector detection through only one sensor. Both of these strategies are analyzed and simulated with the efficient Phase Disposition-Pulse Width Modulation technique. The design and the most important features are highlighted thanks to a digital control frame and a single-phase mock-up rated at 115V/400V - 4kW, 2×31kHz. The presented results also offer a dedicated strategy permitting an optimized real-time reconfiguration in post-fault operation.
