要約(英語): This paper describes characteristics of a multiphase boost chopper on the basis of the difference between its phase number and operation mode. First, this paper presents a theoretical analysis of an input current ripple in a multiphase boost chopper controlled with CCM and DCM. For analysing CCM, the input current ripple in an n-phase boost chopper is expressed by a general formula using a duty ratio. This expression clarifiers integrally the relations between the phase number and input current ripple. The current ripple in CCM is highly reduced than that in DCM for the tested four-phase boost chopper. Furthermore, this paper presents a comparison between the converter efficiency and step response of a four-phase boost chopper controlled in CCM or DCM. The efficiency in CCM is higher than in DCM by 0.5[%]. The phase number affects the step response characteristics in CCM. However, the phase number does not affect the step response characteristics in DCM.
