摘要

本文提出了一种基于载波的PWM (CPWM)方法，用于固定斜率载波信号代替变斜率载波信号的IMC。为了验证所提出的CPWM的通用性，分析了CPWM与空间矢量PWM (SVPWM)的相关性，给出了SVPWM方法中零向量分布与CPWM方法中偏置电压分量类型的关系。此外，根据所提出的CPWM中的偏置电压分量，研究了不同CPWM策略的输出电压波形和开关损耗。最后，对所提出的CPWM进行了实际实施，验证了其有效性。

Generalized carrier-based PWM method for indirect matrix converters

This paper proposes the carrier-based PWM (CPWM) method for IMC with a fixed slope carrier signal instead of a variable slope. In order to verify the generality of the proposed CPWM, the correlation between the CPWM and the space vector PWM (SVPWM) is analyzed and the relationship between the distribution of zero vectors in SVPWM method and the type of the offset voltage component in CPWM method is provided. Furthermore, the output voltage waveform and the switching loss for different CPWM strategies are investigated according to the offset voltage component in the proposed CPWM. Finally, the practical implementation for the proposed CPWM is carried out to demonstrate its effectiveness.
