标题[问题] PWM漏电流解决方法(H5,ac/dc by pass)
时间Mon Dec 19 13:49:39 2016
大家好，想请问有关於单极性PWM漏电流问题
看了几篇paper，用PSIM模拟了我的想法结果都跟paper出来的结果不一样
我觉得我错的地方是不清楚，除了PWM的四个IGBT，多出的两个，要怎麽接控制讯号
以AC bypass方法来说，paper(PV并网)都会讲下列的话，无法体悟到，烦请大家解惑
The operating principle is now explained for a switching period
in the postive grid half cycle, when grid voltage and current are
positives. In the positive grid half cyle, T5 is on. During the
period of time ton=dT T1 and T4 are on.
类似这样，反之就是negative grid half cycle, T6 is on.
想请问有读过的人 可以烦请指点一下吗 谢谢......
