摘　　要：文章针对三维空间矢量PWM调制谐波含量少、可用于四桥臂等特点,重点分析了三维空间矢量调制的原理,对相关矢量发生的算法进行了详细推导;并利用MATLAB/SIMULINK仿真软件进行了仿真,仿真结果验证了三维空间矢量PWM调制算法的正确性。The principle of three-dimensional space vector PWM（3DSVPWM）, which is often used in the topology of three-phase four-leg inverter, is introduced. In the 3DSVPWM strategy, the output voltage can be synthesized from the reference vector although its load is unbalanced. The algorithm of 3DSVPWM pulse generation is studied in detail. The developed algorithm is simulated in MATLAB/ SIMULINK. The results confirm the validity of the algorithm.
