电源元器件安规温升资料

3 •温升测试

60950 — 4.5.1 条款，现在新版本 IEC60950_1:2005

――测试条件：

1）在正常负载情况下，最小输入电压和最大输入电压测量。

2）室温。

测量方法：

热电偶法和电阻法，一般是热电偶法。

――测量元器件：

1）原则：安全关键件和发热量大的器件（热电偶法）

必布的点：室温

PCB/PWB、铝基板

光耦

X/Y电容变压器绕组/电感绕组（发热量大的地方）-磁材和绕组，一般取绕组外壳（除开放式外）

插头、插座

电线/引线

其余：控制芯片

跨接电容

MOS管

60950中1412.3条）计算值

其它发热量大的器件，

――热电耦法测量的温度，不允许超过以下公式（

1）变压器绕组

Tmax + Tamb — 10— Tma

（测量的温度）（标准中允许（室温）（电源最高

的最大温度环境温度）

查表4B/4C）

2）除变压器绕组外，其它器件

T < Tmax + Tamb — Tma

公式说明：

Tmax依据见下表4B,4C;

Tamb依据热电耦测的当时的室温；

Tma依据电源模块给客户承诺的工作温度（如果电源有降额曲线，而且是线性的，取开始降额使用的那点值）

――在这个公式中，决定温升是否合格的重要因素，就是给客户承诺的电源的最高环境温度。
