Four phase interleaved boost converter - analysis and verification

Anotace: This paper deals with an analysis of four phase interleaved DC-DC converter for higher power application in continuous conduction mode. The interleaved topology is widely used due to their advantage as lower input current ripple which means volume reduction of input capacitor. The current ripple equation of an input current for the boost operation mode and the ripple current in individual phases of the interleaved converter using uncoupled inductor are shown. The theoretical equations are supplemented by the simulation results using Spice simulator and by measurement on the interleaved converter.
