IC200PWR102扩展模块
辅助电路有什么作用?
答:300V直流电通过辅助电源开关管成为脉冲电流,通过辅助电源变压器输出二组交流电压,一路经整流、三端稳压器稳压,输出+5VSB,加到主板上作为待机电压;另一路经整流滤波,输出辅助20V电源,供给PWM等芯片工作。有了辅助电路,计算机就可以实现软件开机、关机了。

回波损耗:在高频场合,反映行波在保护设备的过渡点处被反射的比例,在这一参数下可直接衡量,保护器件与系统的涌波阻抗的匹配程度,对于数据传输系统,为防止位错误,系统的回波损耗大于20dB。
大放电电流(Imax):避雷器承受8/20波形的测试电流,而不引起损坏,保护器能承受2次这样的大电流。
