实际并不放电；对于小功率的变频器很有放电电阻损坏欠电压保护产生欠电压的原因及处理方法：①电源电压太低②电源缺相；③整流桥故障：如果六个整流二极管中有部分因损坏而短路，整流后的电压将下降，对于整流器件和晶闸管的损坏，应注意检查，及时更换。逆变器件的介绍：1.SCR和GTO晶闸管⑴普通晶闸管SCR曾称可控硅，它有三个极：阳极，阴极和门极。SCR的工作特点是，当在门极与阴极间加一个不大的正向电压（G为+，K为—）时，SCR即导通，负载Rl中就有电流流过。导通后，即使取消门极电压，SCR仍保持导通状态。只有当阳极电路的电压为0或负值时，SCR才关断。所以，只需要用一个脉冲信号，就可以控制其导通了，故它常用于可控整流。
