努力提高开关电源的可靠性

Inprove the Reliability of Switch Power Supply

开关电源在工作过程中,一是内部的器件工作在大电流、高电压应力的开关状态,运行环境非常恶劣,同时,在运行过程中会受到各种外界因素的影响。因此,如何减少设计缺陷、保证开关电源可靠性就成为开关电源设计的重要方面。本文通过对开关电源外界影响的分析,介绍了测试需要考虑的内容。

When the switch power supply is working, due to the switching condition of the high-current high-voltage stress the internal components will be exposed to tough operating environment and also its operation will be affected by external factors. Thus, it is an important aspect for designing of switch power supply to reduce design flaws and ensure its reliability. The article introduces factors to be concerned for testing, following the analysis of external influences toward switch power supply.
