摘　　要：利用动态死区时间控制技术,通过对电源电压、输出负载和元器件容差对逆变器性能的影响进行理论和实践分析与研究,采用检测逆变器供电电源及负载电流并利用其数值来调制逆变器延迟电路的延迟时间,从而使逆变器的死区时间处于最优状态,在提高了逆变器的效率和动态性能的同时改善了电网质量。其性能在变频电梯实际应用中得到验证。Using the dynamic dead time control technology, through the theoretic and practical analysis and research on the power supply, output load and component tolerances on the performance of the inverter, the power supply of the inverter and the load current were detected and the values were used to modulate the delay time of the inverter delay circuit, so that the dead time could be in the optimal state to improve the efficiency and dynamic performance of inverter, and also power quality. Its performance in the practical application of variable lift was proven.
