Abstract

This paper presents harmonic mitigation techniques for hybrid electric vehicle traction motor drive systems. First, DC-bus harmonics are presented for a space vector modulated (SVM) dual traction drive system, compared against military standard MIL-STD-461. Next, dithered/random SVM techniques are explored and the respective harmonic performance is compared. The effect of the DC-bus capacitor size is also fully investigated, with the harmonic results again compared against MIL-STD-461. Based on the overall results and inherent DC-bus resonance conditions, it is proposed that the harmonic performance can be optimized through strategic frequency selection within the random switching frequency pool. Therefore, the paper concludes with analysis and implementation of "selective" switching frequency sweeps.
混合动力汽车直流母线牵引传动的谐波缓解技术
介绍了混合动力汽车牵引电机驱动系统的谐波缓解技术。首先给出了空间矢量调制(SVM)双牵引驱动系统的直流母线谐波,并与军用标准MIL-STD-461进行了比较。其次,探讨了抖动/随机支持向量机技术,并比较了各自的谐波性能。对直流母线电容尺寸的影响也进行了充分的研究,并将谐波结果再次与MIL-STD-461进行了比较。在综合研究结果和直流母线固有谐振条件的基础上,提出了在随机开关频率池内通过战略性频率选择来优化谐波性能的方法。因此,本文最后对“选择性”开关扫频进行了分析和实现。
