Abstract

This brief proposes an improved pulse width modulation (PWM) scheme, which uses diode voltage clamping characteristics to achieve the direct control of three‐phase current source converter without any logical transformation. Compared with the traditional indirect carrier modulation scheme—mapping‐PWM, the proposed scheme can solve the disadvantages of low DC current utilization, high switching loss, and complex control process. The generation mechanism of IPWM is analyzed in this brief. Then, based on the generation mechanism, the output characteristics of the system under IPWM are analyzed and compared with the traditional modulation scheme. Finally, the experimental results verify the effectiveness the proposed modulation scheme.

三相电流源转换器的新型调制方式

本文提出了一种改进的脉宽调制（PWM）方案，该方案利用二极管电压箝位特性实现对三相电流源变换器的直接控制，无需任何逻辑变换。与传统的间接载波调制方案-映射-PWM 相比，该方案解决了直流电流利用率低、开关损耗大、控制过程复杂等缺点。本文简要分析了 IPWM 的产生机制。然后，根据生成机制分析了 IPWM 下系统的输出特性，并与传统调制方案进行了比较。最后，实验结果验证了所提出的调制方案的有效性。
