摘要:
由于高压变频器(HVI)拓扑结构及调试算法的特殊性,需要考虑从主控PWM源进行统一的死区补偿,而非每个功率单元独自进行死区补偿。为此,文章首先介绍了级联型高压变频器系统拓扑和功率单元结构;然后着重分析了不同电流方向及开关状态以及中性点不同接入方式时死区对载波移相调制下级联型高压变频器单个功率单元的影响,接着扩展至高压变频器所有单元,在此基础上给出相应的死区补偿策略;最后通过在高压变频器样机上实验,验证了该策略对于开环VF 控制以及闭环矢量控制下死区补偿的有效性。
Abstract:
Because of the particularity of high voltage inverter(HVI) topology and algorithm, the uniform dead time compensation should be considered from the main control PWM, instead of respective dead time compensation for each power unit. Therefore, it first introduced the topology structure of high-voltage inverter system and its power unit, and then mainly analyzed the different directions of current , switch states and the different connecting ways of neutral points. Based on the analysis of dead time on how to influence the individual power unit of cascaded high-voltage inverter under carrier phase shift modulation, all the units of high-voltage inverter were involved, and then a dead time compensation strategy was put forward. Finally, through the experiment on the high-voltage inverter, it verified the effectiveness of the dead time compensation strategy in open loop VF control and closed loop vector control.
