| 摘 要： | 该论文详细分析了电压型PWM逆变器死区对输出电压和输出电流的影响,并基于预测电流控制算法,提出了一种新的补偿算法,对电压损失进行补偿.以达到使最终的输出电流跟踪于期望电流的目标。最后把该算法应用在SVPWM逆变电路中,进行了仿真和实验板的调试,仿真分析和实验结果都表明该算法对死区补偿具有良好的有效性和可行性,并且补偿算法完全由DSP完成,不需要增加硬件电路。

| Abstract: | This paper analyses the effect of dead time on the output voltage and current in voltage-source PWM inverter.Based on predictive current control,a novel compensation algorithm is proposed to compensate for voltage loss so that the final output current can track the aim current.Finally,this algorithm is applied in SVPWM inverter with experiment board.The simulation analysis and experimental results verify the good validity and feasibility of the novel algorithm.The compensation algorithm is completely implem... |
