Abstract :
This paper presents the analysis and design of integrated magnetics (IM) for a 3-phase interleaved boost DC-DC converter for series hybrid electric bus. The converter is designed to meet both 30 kW average and 120 kW peak power demand of bus. The input and inductor current ripple of IM are calculated theoretically and compared with experimental waveforms. In order to minimize the core and winding loss of IM, the core height is minimized. Experimental results are presented to prove and to show the performance of IM.
