Abstract :
The patentees of the SPARC patent, from FAIVELEY Transport, propose a new structure of interleaved converter. The interlacing of the switch controls removes the discontinuities in the input and output electric signals, which present a weak ripple signal at high frequency, therefore reducing the size of the associated filters. The principle of operation is illustrated, with a steady state analysis for a DC to DC converter. The effectiveness of the proposed converter topology is verified by implementing a 1 kW - 20 kHz hardware simulator using IGBTs and fast recovery diodes.
