| 摘 要： | 基于空间矢量脉宽调制(SVPWM)与对称采样零序信号注入正弦脉宽调制(SPWM)是等效的这一理论,提出了一种基于零序偏移时间(ZSOT)的载波型空间矢量脉宽调制方法,运算速度明显快于传统的空间矢量脉宽调制算法,极易在中低档次的微处理器上数字化实现.仿真结果验证了所提出方法的正确性和优越性.

| Abstract: | It proves that the space vector pulse-width modulation(SVPWM) is equivalent to a particular form of regular-sampled pulse-width modulation based upon adding a particular form of zero-sequence component to the sinusoidal modulating wave. According to this theory,a carrier-based space vector pulse-width modulation method based on zero-sequence offset time(ZSOT) was described.It can be easily implemented by a low-performance microprocessor,and the executing speed is obviously faster than the traditional SVPWM.The simulation results confirm the correctness and advantages of the proposed method. |
