本文根据多相升压斩波的相数和工作方式的不同，描述了多相升压斩波的特性。本文首先对CCM和DCM控制的多相Boost斩波器的输入电流纹波进行了理论分析。对于CCM的分析，n相Boost斩波器的输入电流纹波用占空比的一般公式来表示。该表达式完整地阐明了相数与输入电流纹波之间的关系。对于所测试的四相升压斩波器，CCM中的电流纹波比DCM中的电流纹波要小得多。此外，本文还比较了CCM和DCM控制的四相Boost斩波的变换效率和阶跃响应。CCM的效率比DCM高0.5个百分点。相位数影响连铸机的阶跃响应特性。但不影响DCM的阶跃响应特性。《电子期刊》，185(1)：57-66,2013；在线出版于Wiley在线图书馆(wileyonlinelibrary.com)。DOI 10.1002/eej.22398
This paper describes the characteristics of a multiphase boost chopper on the basis of the difference between its phase number and operation mode. First, the paper presents a theoretical analysis of an input current ripple in a multiphase boost chopper controlled with CCM and DCM. For analyzing CCM, the input current ripple in an n‐phase boost chopper is expressed by a general formula using a duty ratio. This expression clarifies integrally the relations between the phase number and input current ripple. The current ripple in CCM is much lower 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 that in DCM by 0.5%. The phase number affects the step response characteristics in CCM. However, it does not affect the step response characteristics in DCM. © 2013 Wiley Periodicals, Inc.
