摘要
基于传输线理论 ,研究在不同载波频率下电机特性变化对电机端电压的影响。在理论分析和实验验证的基础上 ,通过在电机端加入阻抗匹配网络 ,有效抑制过电压的产生。
Based on the transmission theory, the effects of the variant characteristics of motors on the motor terminal voltage are analyzed with different carrier frequency. The plural frequency field analysis of the equivalent circuit of the motor and the Fourier transform of the pulse wave are applied to probe into the high frequency characteristic of the motor in this paper. By theory analysis and experiment verification, an impedance matching network is fixed at the motor terminal, which is valid to reduce the over voltage.
