摘　　要：详细分析了PWM逆变器的死区效应和常用的补偿死区的方法。基于预测电流控制算法提出了一种新的补偿算法。经仿真分析和实验结果证明,该算法能有效补偿死区效应,而无需添加任何硬件,所有算法都由DSP完成,易于实现。The paper analyzes the dead time effects of the PWM voltage sourse inverter.Based on the analysis of several normal compensations,a modified predictive current control is introduced that compensates the voltage loss due to dead time and reduces the zero current clamp problem caused by dead time.The validity and feasibility of the proposed algorithm are confirmed by experimental implementation.
