大家好,想請問有關於單極性PWM漏電流問題 看了幾篇paper,用PSIM模擬了我的想法結果都跟paper出來的結果不一樣 我覺得我錯的地方是不清楚,除了PWM的四個IGBT,多出的兩個,要怎麼接控制訊號 以AC bypass方法來說,paper(PV併網)都會講下列的話,無法體悟到,煩請大家解惑 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. 類似這樣,反之就是negative grid half cycle, T6 is on. 想請問有讀過的人 可以煩請指點一下嗎 謝謝...... -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 140.113.186.245 ※ 文章網址: https://www.ptt.cc/bbs/Electronics/M.1482126582.A.451.html
