摘要：

This paper presents a fault tolerant control strategy for a three-phase interleaved boost converter applied to renewable energy systems. The structural and operational characteristics of the three-phase interleaved boost converter are described. By interleaving the switching circuit patterns, the input current and the output voltage ripples can be significantly decreased without increasing the switching losses, resulting in the satisfactory converter efficiency. The power and current ratings of each switching components can be lowered. The fault tolerant control strategy with Proportional Integral (PI) controller plus a phase-shift technique for the three-phase interleaved boost converter under healthy and faulty operating conditions is detailed. The simulation results are shown to demonstrate the effectiveness of fault tolerant control capability for the three-phase interleaved boost converter under normal and open-circuited switch failure operations.
