新手求助，

                                                                我想做一個(gè)2000w的純正弦波逆變器后極，后極就差電感了，

                                                                可我對(duì)電感不怎么懂，

                                                                所以來論壇求助，

                                                                后級(jí)我想弄成一個(gè)電感的，電感量我想弄1.2mh的夠嗎？

                                                                還有磁心可以選什么型號(hào)的

                                                                對(duì)了，電腦電源里面的那個(gè)大又重的電感可不可以代替這個(gè)啊

                                                                知道的回復(fù)問一下吧，謝謝了
