中文摘要：

实现了基于数字信号处理器（Digital Signal Processor-DSP）的空间矢量脉宽调制（Space Vector Pulse Width Modulation——SVPWM）系统，并将其应用于电压型整流器（Voltage Source RectifierVSR）触发系统中。相比较于其它脉冲宽度调制技术，采用的SVPWM具有算法简单、适用于数字实现、电压利用率高、开关损耗小以及硬件电路简单等特点。实验结果表明，设计的基于DSP的SVPWM脉宽调制系统达到VSR触发系统的要求，为VSR装置正常、有效地工作提供了重要保证。

英文摘要：

Implementation of a DSP-based SVPWM pulse width modulation system can be used in VSR triggering system. Compared to other pulse width modulation technology, the Space Vector PWM （SVPWM） in this paper has some characteristics such as simple algorithm, application in the digital realization, high volt- age utilization, small switching losses and simple hardware circuit etc. It is shown by the experimental results that the DSP-based SVPWM meets VSR triggering system requirements, provides an important guarantee for normal and effective working of VSR.
