【摘要】 本文运用数字仿真方法，计算、讨论了PWM逆变器的控制参数（加载波频率、输出电压基波频率和调制度）对死区效应的影响，并用实验方法验证了理论分析的结果。本文得出的结论对于深入研究，提高PWM逆变器的性能，以及正确、有效地使用由其构成的各种交流传动装置（如变频器）是非常有用的。更多还原

【Abstract】 The authors calculate and discuss the influence of the controlling parameters of PWM inverters (carrier wave frequency, fundamental frequency of output voltage and modulatlon coefflcient) On dead t1me effects by the aid of digitalsimulation method in this paper. The experimental results have verified the theoretical analyzing ones. The conclusions in the paper are very useful to improving performance of PWM inverters, and to making use of variable speed AC drives withPWM effectively.更多还原
