A six-phase bi-directional interleaved converter

This paper investigates the operation of a bi-directional interleaved converter. The DC-DC converter can operate both as a buck and a boost converter as per operating requirements. Design methodology for the converter operating in either modes is presented in detail. Analysis on duty cycle limits, voltage conversion ratios and efficiency including non-idealities of the converter is presented. Extensive simulation and experiment results corroborate the theory.
