作用及工作原理：

續流二極管都是並聯在線圈的兩端
，線圈在通過電流時
，會在其兩端產 生sheng感gan應ying電dian動dong勢shi。當dang電dian流liu消xiao失shi時shi，其qi感gan應ying電dian動dong勢shi會hui對dui電dian路lu中zhong的de元yuan件jian產chan生sheng反fan向xiang電dian壓ya。當dang反fan向xiang電dian壓ya高gao於yu元yuan件jian的de反fan向xiang擊ji穿chuan電dian壓ya時shi，會hui使shi元yuan件jian如ru三san極ji管guan
