摘　　要：在分析三相SVPWM逆变器死区时间内工作过程基础上,采用了一种基于死区优化设置法消除死区效应的策略。该策略通过对电流极性的判断,只对逆变器每相桥臂上的某一个开关管加入死区,并通过仿真和实验验证了理论分析的正确性和补偿措施的有效性。The performance process of three-phase SVPWM inverter in the dead time is analysised, and a strategy to eliminate the dead-time effects based on optimal setting of dead time is applied. Dead time is only added to one switching device of every bridge leg of the inverter according to the judgement of the current polarity, and the correctness of the theoretical analysis and the effectiveness of compensation measures were verified by emulation and experiment.
