Abstract :
Interleaved discontinuous conduction mode (DCM) three-phase boost rectifiers provide current ripple cancellation and increase the effective frequency of the input current ripple. As a result, the size and cost of the differential mode (DM) input filter is reduced. This work presents a detailed analysis of the input current ripple of interleaved three-phase DCM boost rectifiers. The design curves derived from the analysis are used to determine the DM input filter parameters. The experimental results are shown for two interleaved three-phase DCM boost rectifiers rated at 8 kW of total power and operated at 40 kHz with IGBTs as the main power switches. The results show that the interleaved rectifiers comply with the IEC 61000-3-2 Class A harmonic standard for this power level
