摘要
电视和显示器的电源经常出现PWM芯片和主MOS管烧毁的不良现象。数据显示,此现象在雷雨季节尤其明显。在大量试验的基础上,介绍一种新的避免雷击失效的电源线路。市场数据证明,此线路具有有效性。
PWM chips and main MOS often failed in the power supply system of TV and monitor,and a large amount of data shows that this phenomenon is particularly obvious during thunderrain season. On the basis of a large number of tests,a new power line to avoid lightning failure is introduced. Market data prove that this line is very effective.
