一、电源板是什么

电源板，顾名思义就是一种处理电源的主板。电源板在很多的电子产品里面都会使用到，包括我们的电脑、手机以及平板

电脑等等都会使用到电源板。电源板对于电子产品是非常重要的，所以市场上也有很多品牌的电源板，他们有好有坏，需要我

们在购买的时候仔细辨别。

二、电源板工作原理是什么

1、通电后副电源首先启动工作，为主电路板微处理器控制系统提供正5伏的工作电压。

2、开机后，副电源为PFC功率因数校正电路驱动控制电路UCC28051、主开关电源驱动巨制电路DLA001的提供VCC一

ON供电，主开关电源启动工作，向主电路板负载电路提供正24伏和正12伏两种电压。

3、经过抗干扰电路滤除市电中的杂波干扰，整流、PFC电感、滤波输出300V直流电压到副电源电路，副电源开始工作输

出+5v电压。

4、经电源板输出排插端口1脚到数字板CPU电路，CPU电路经过读取数据开机输出高电平开机电压。

5、经电源板排插端口2脚到电源板稳压开关机控制电路，开关机控制电路工作，输出电压到PFC振荡电路，输出高频方

渡脉冲推动PFC开关管工作，利用PFC电感产生的逆程脉冲。

6、经过整流、滤波生成400V的PFC电压。PFC电压送到主电源电路和PFC电压检测电路，PFC检测电路检测到PFC电压

达到400V，PFC检测开关电路输出电压到主电源震荡电路，振荡电路输出高频方波脉冲到主电源功率开关管电路。

7、开关管工作推动开关变压器工作，从次级感应输出2组电压，经过整流、滤波输出+12V、+24V电压。到此，整个电源

板启动过程完成。

8、电视待机时，采用切断PFC功率因数校正电路驱动控制电路UCC28051、主开关电源驱动控制电路DLA00I的VCC一

ON供电，主电源停止工作。
