Summary:This paper investigates the behavior of the three-phase interleaved boost converter for renewable energy system under open-circuited switch fault conditions. It is expected that the faulty switches of the converter can be correctly detected in a very short time by taking the consideration on the converter behaviors under various operation conditions. In this paper the three-phase interleaved boost converter topology is firstly described. The PI controller is then properly designed in order to obtain the satisfactory converter performance. The phase-shift technique is also employed for ripple cancellation purpose, resulting in small ripples in the inductor currents and the capacitor voltage. Finally, the simulation results show the behavior investigation of the interleaved boost converter under healthy and faulty switch operating conditions. The input current, the output voltage and three inductor currents are deeply considered in order to develop the appropriate fault detection strategy for the future work.
