摘要 为抑制三相变流器共模电流,首先提出一种通用型最近三矢量脉宽调制(GNSPWM)策略,并阐述了其矢量合成思想,然后从线性可调制区、谐波畸变率和开关损耗3个方面对各种具有共模电压抑制能力的调制策略性能进行比较分析,结果表明所提调制策略在抑制共模电压的同时,不仅具有谐波含量小的特点,还可进一步降低变流器侧非单位功率因数条件下的器件开关损耗。为方便应用,给出所提调制策略的载波比较实现方法。最后,通过实验样机平台对所提调制策略进行实验验证,结果表明,在等效开关频率相同的前提下,所提调制策略在抑制共模电压、降低损耗方面均具有一定优势。 To suppress common-mode current of three-phase converter, a generalized near state pulse width modulation (GNSPWM) method is proposed.Then its vector synthesis pattern is described.then detail performance analysis of the method is provided and it is compared to the other methods in linear modulation region ,harmonic distortion and switching loss.It proves that the proposed modulation strategy in addition to a low common-mode voltage, small har- monic content features, it also can further reduce the switching losses under non-unity power factor conditions of inverter.Finally, the proposed modulation strategies is tested in the experimental inverter platform, the result show that, under the same equivalent switching frequency ,the proposed modulation strategy has advantages in suppressing of common mode voltage and reducing switching losses.
