用万能板制作逆变空载电流会大!!!!!
用一块9*7CM万能板制作SG3525+一对IRF3205,初级5+5,次级160.试机接100W灯200V不够. 空载时把频率调低一点8A电流,高时1A电流.5到7脚电阻为100欧,5脚对地电容为222,6脚为100K可调.请各位师傅指点下!先谢了..........

首先谢楼上各位高手的指点先喔!从表面看SG3525应该是正品,5元一只.磁隙磨平,没虚焊,那我试下改变CT容量吧.我估计应该与万能板没关...
看我的,磁芯是EC40,3525+3205两队.前级空载130MA.加后级150.带风扇一共啊200MA.变压器是0.7*8*4匝俩组.次级0.5*2 大概100匝
