浅谈大功率功放的温升控制

Preliminary Discussion on Temperature-rising Control of High Power Amplifier

在功率放大器的型式试验中经常会遇到温升不合格的问题,这些问题给使用者带来一定的安全隐患。针对这些问题,我们可以从功放的热源方面控制它的温升,也可以在电路设计中加上温控和保护功能,通过这些措施使它的温升控制在允许的范围内。

The temperature rises exceeding the limited value usually happened during the type test of the audio amplifier. We can prevent it by controlling the heating source adding some protector and temperature controller in the circuit diagram.
