摘要
在分析谐波电流工作机理的基础上,提出了一种永磁同步电动机逆变器供电的谐波等值电路及谐波电流计算公式,介绍了谐波等值电路中电阻、电感参数的计算方法。样机计算值与试验测量数据基本吻合,验证了该谐波模型的可行性。
Based on the harmonics current operation principle of inverter power supply of permanent magnet synchronous traction motor, a harmonic equivalent circuit and harmonic current formula were presented. The calculation method of the harmonic equivalent circuit resistance and inductance parameter was introduced. The result of calculation coincided with test measurements, harmonics model feasibility was validated.
