我是业余玩的,因为有充足的时间,捡到一堆垃圾

想用12V做1000W,真的好难.只能做到800W,
1:输入线与主变连接有很大的压降,主变的工艺要很好.
2:并管难,以上我的4对3205都是全新的一至的,曾经用过不一至的管,其中个别发热,很是头痛.
3:如要闭环稳压,必须在高压整流与滤波电容间串联电感,我用EE42/1.0线绕150圈,否则3205的温度一直上升.
4:为了保险,必须加风冷.
我的主变规格:EE55加厚,频率=25KHZ,输入组=2T(0.5线/12*4组=48条)+2T(0.5线/12*4组=48条),输出线用0.5线*10条/45T,绕法是先绕输入组后绕输出组.
主变输入组的出线一定不能大意,我曾经电烙铁功率不够,造成包线而两边不对称,后用大功率电烙铁把线头全部上锡后再焊上.
管与散热片要处理好,绝缘片不要太厚,最好加散热胶,曾经试过管很热而散热片一点都不热,造成走弯路.
