摘要/Abstract

摘要： 针对三电平 DC-DC 变换器开关数目多开关模态复杂难以用传统建模方法对之进行统一建模用脉冲波形积分法对三电平 DC-DC 变换器进行建模分析得到了有效的统一模型．文中以 Buck 三电平 DC-DC 变换器为例详细阐明了统一建模原理并给出了三电平 DC-DC 变换器的统一建模方法．仿真分析与实验验证了理论分析的结果表明基于脉冲波形积分法对三电平 DC-DC 变换器进行统一建模是行之有效的．

关键词: 三电平变换器, 统一建模, 冲波形积分法, 周期性脉冲函数

Abstract:

The three-level DC-DC converter is known to have too many power switches and complex operation modesand it is difficult to obtain a unified model by using conventional modeling approaches．In view of such disadvantagesa novel unified modeling approachthe pulse waveform integral approach was used for the first time to analyze the converter．With the unified modeling of Buck three-level DCDC converter as an examplethe modeling principle was investigated in detail．Also the unified modelng of other three-level DC-DC converters can be deduced．The simulation analysis and experiment results indicate that the pulse waveform integral approach to the unified modeling of three-level DC-DC converters is both effective and efficient．

Key words: three-level converter, unified modeling, pulse waveform integral approach, periodic pulse function
