针对单相三电平中点箝位型(NPC)整流器中多个开关管同时导通或关断的问题
在分析电路拓扑和工作原理的基础上
提出了一种单相空间矢量脉宽调制(SVPWM)方法。这种SVPWM方法合理地设计各个扇区内部的调制序列
并且在扇区切换时加入过渡调制序列
从而保证了开关状态的连续性。在分析各个开关状态对中点电压影响的基础上
该方法根据中点电压和网侧电流的情况来选择合适的冗余小矢量
从而实现直流侧中点电压控制。另外
通过使用冗余零矢量
该方法能够达到倍频的效果。针对这种SVPWM方法
搭建样机进行了实验研究
实验结果表明:SVPWM方法能够保证在同一时刻只有一个开关管导通或关断
而且输出电压的跳变量为直流侧电压的1/2; 网侧电压与网侧电流保持了较好的同相位
且动态性能良好; 该方法能够实现中点电压控制
并且具有较好的动态响应速度和稳态控制精度。
Aiming at the problem of multiple switches simultaneous turning on or off in single-phase three-level neutral point clamped(NPC)rectifiers
we put forward a space vector pulse width modulation(SVPWM)method. This method can reasonably design the modulation sequences inside each sector
and add transition modulation sequences in sector switch
so as to ensure the continuity of switching states. On the basis of analyzing the influence of each switching state on the neutral point voltage
this method selects appropriate redundant small vector according to the neutral point voltage and grid current
so as to achieve the neutral point voltage control. In addition
by using redundant zero vectors
this method can achieve the effect of frequency doubling. For this SVPWM method
a prototype was built to carry out experimental research. The experimental results showed that the proposed SVPWM method can guarantee only one switch turning on or off at one time
and the change of the output voltage is always half the DC side voltage
and that the phase of the grid voltage is the same as that of the grid current
with good dynamic performance. This method can realize the neutral point voltage control with fast dynamic response speed and accurate steady control.
