Abstract :
In interleaved converters, the commutation cells can be interconnected by intercell transformers. In this paper we show how a modified sequence of the voltages applied to windings reduces the flux density in the magnetic core branches. Experimental measurements confirm the flux reduction obtained with the modified supply. Thermal measurements were made in order to evaluate the reduction of total core losses when the modified supply is used.
