摘　　要：在逆变系统中,死区导致逆变器的输出波形发生畸变,即死区效应.文中在对死区效应进行量化分析的基础上,提出一种基于新型开关策略的死区补偿技术.该方法通过实验验证,实验结果证明了该方法的实用性和有效性.The dead-time inserted into the switching signals of inverters case the dead-time effect of output voltage distortion. The influence of dead-time on output voltage in inverters is analyzed in detail, Then, a new switching strategy, which can provide excellent inverter output voltage distortion correction, is proposed. At last, the experiment results of inverter are presented to demonstrate the practicability and validity of the control strategy.
