我是做电源的,手里有些材料,想做台功率不是很大的高频电焊机,能在家里焊个铁架子什么的就行,请各位做电焊机的老大提供些方案,要求,比如电压,电流,电路结构; 本人想用SG3525的双管(4个47N60)交错正激,变压器用EC49的2个,变压比25比5,整流管用MUR3060,四个整流,四个续流,输出电容100V1000UF四个,空机电压60V,输出采用80安限流降压方式
双正激的输出电压不易稳定在60v,变压器的绕制困难,如果要求2.5mm焊条
60%占载率.推荐rl的桥式,或单端双管,
单端双管输出电压高易起弧且自带电弧推力,

这个波形是哪里的,上面的波形挺好,做这样不容易.

我用的25n120d,功率管加36v时的驱动波形.如果用f450,波形跟这不一样.没有尖角,

推动功率不足,改一下推动变压器,会有好效果.
