A novel phase shedding control algorithm considering maximum efficiency for 3-phase interleaved boost converter

Abstract

A novel phase shedding control algorithm considering maximum efficiency for 3-phase interleaved boost converter is proposed. The phase shedding control algorithm is performed to control the operating phase of interleaved converter in accordance with wide load range for high efficiency. Conventional interleaved converter has low efficiency under the light-load condition. In this paper, the 3-phase interleaved boost converter has wide load range by the phase shedding algorithm to the interleaved converter, the validity of proposed phase control algorithm considering efficiency for 3-phase interleaved boost converter is verified by simulation results.
