一种旨在减轻反射波现象引起的电机过电压的输出电压畸变最小化PWM技术

This article introduces a PWM technique to minimize output voltage distortion for mitigating motor overvoltage caused by the reflected wave phenomenon. When high dv/dt switches are used in motor drive systems with long transmission lines, impedance mismatch leads to voltage reflection, which causes overvoltage at the motor terminals. To suppress this overvoltage, various PWM-based techniques have ...
