The high-power traction inverter allows for a lower switching frequency. To improve the output performance of a system, synchronous space vector pulse width modulation (SVPWM) strategies are usually used in the medium-speed range, and four synchronous modulation strategies with different performances can be flexibly implemented based on the number and positions of sampling points, as well as the sampling point vector action order. Under this background, the basic principle of four synchronous SVPWM strategies is summarized at first, with a focus on the smooth and shock-free switching method between different frequency-division and different modulation strategies. Second, to address the issue of fundamental phase discontinuity between the boundary sampling strategy and other modulation strategies during the switching, a method is proposed to split the original sampling sector and further reassemble into a new sector, which not only achieves phase continuity but also makes the setting of carrier wave ratio more flexible. Finally, the feasibility of the proposed method was verified by simulation and experimental results.

大功率牵引逆变器允许开关频率较低,为了提高系统的输出性能,中速区通常采用同步空间矢量脉宽调制SVPWM(space vector pulse width modulation)策略,可根据采样点个数、采样点位置及采样点矢量作用顺序灵活实现4种性能各异的同步调制策略。为此,首先概述了4种同步SVPWM策略的基本原理,重点对不同分频、不同调制策略之间的平滑无冲击切换方法进行了分析。其次,针对边界采样策略与其他调制策略在切换时基波相位无法连续的问题,提出了1种对原始采样扇区进行拆分并重新组合成新扇区的方法,既实现了相位连续,也使得载波比设置更加灵活。最后,通过仿真及实验验证了所提方法的可行性。

大功率牵引逆变器允许开关频率较低,为了提高系统的输出性能,中速区通常采用同步空间矢量脉宽调制SVPWM(space vector pulse width modulation)策略,可根据采样点个数、采样点位置及采样点矢量作用顺序灵活实现4种性能各异的同步调制策略。为此,首先概述了4种同步SVPWM策略的基本原理,重点对不同分频、不同调制策略之间的平滑无冲击切换方法进行了分析。其次,针对边界采样策略与其他调制策略在切换时基波相位无法连续的问题,提出了1种对原始采样扇区进行拆分并重新组合成新扇区的方法,既实现了相位连续,也使得载波比设置更加灵活。最后,通过仿真及实验验证了所提方法的可行性。

The high-power traction inverter allows for a lower switching frequency. To improve the output performance of a system, synchronous space vector pulse width modulation (SVPWM) strategies are usually used in the medium-speed range, and four synchronous modulation strategies with different performances can be flexibly implemented based on the number and positions of sampling points, as well as the sampling point vector action order. Under this background, the basic principle of four synchronous SVPWM strategies is summarized at first, with a focus on the smooth and shock-free switching method between different frequency-division and different modulation strategies. Second, to address the issue of fundamental phase discontinuity between the boundary sampling strategy and other modulation strategies during the switching, a method is proposed to split the original sampling sector and further reassemble into a new sector, which not only achieves phase continuity but also makes the setting of carrier wave ratio more flexible. Finally, the feasibility of the proposed method was verified by simulation and experimental results.
