| 摘 要： | 针对数字控制技术的特点，分析了在选择性谐波消除法的理论计算结果与实际开关角数字控制结果出现偏差时，对逆变器输出电压谐波含量的影响。并研究了开关角数量对逆变器性能的影响，结果表明：开关角控制误差对逆变器输出谐波有一定影响，但可以在计算时修正；而开关角数量的增加有利于减小电流脉动，提高输出电压质量，但开关频率随之增加。

| Abstract: | This paper analyzes the influence of the error between the calculated results by selective harmonic elimination and the digit_controlled results on the output of inverter. It also studies the effect of the number of the switching angles on the inverter performance. The results show that the control errors affect the inverter output_vltage but can be reduced in the calculation period. The study has proved that the current ripple can be reduced and the output voltage quality can be enhanced by increasing the numbers of switching angles, but in the meantime, the switching frequency is heightened. |
