电源是HP部门级PENTUIMPRO服务器上拆下的,虽然是老东西,但是
用料巨好,额定最大350W竟然用了直径5CM的变压器,低压输出甚至
用了10000uF的电容.电源参数是:+5V 37A +3.3V 12A 12V 10A ,
现在想把+12V提升到20A.变压器+12V绕组为4根1mm漆包线并绕,
这里不打算改动.原快恢复管是D92-02(20A200V),打算并联一只.
让我头痛的是这一路中的2个线圈.
电感L151(15x8x6外径内径高)不知是磁放大器还是尖蜂抑制器,用2根
多芯线并绕了14匝,磁环材料未知,青灰色表面很粗糙,电子市场买
不到类似的磁环,有一家说可能是“铁钼铝”.扼流电感L152(磁粉芯
28x14x12),29匝,线径1.2MM.在电子市场找人测试,L151电感量约
17uH(不很确定),L152是88uH(确定).L151因为买不到相同材料的,
只能用原磁环.买了一个铁粉芯磁环打算替换L152,尺寸38x21x11.
把+12V电流提升到20A,这2个电感应该各绕多少匝?万分感谢!
